Two events are independent if the occurrence of one doesn’t affect the probability of the other.
In other words, the events are not related.

Introduction
Two events are mutually exclusive if they can’t happen at the same time. In other words, if one event happens, the other can’t. For example, mutually exclusive events could be drawing a black card or a red card from a deck of cards.
Mutually exclusive events are also called disjoint events.
Independent events are events that aren’t affected by other events. For example, rolling a die and flipping a coin are independent events because the outcome of one doesn’t affect the outcome of the other.
So, are mutually exclusive events independent? The answer is no; they’re not independent because they’re not affected by otherevents.
What are Mutually Exclusive Events?
Mutually exclusive events are two events that cannot happen at the same time. For example, flipping a coin and getting a head is a mutually exclusive event with flipping a coin and getting a tail. Two events are only mutually exclusive if they cannot happen at the same time.
Two Types of Events
There are two types of events: those that are mutually exclusive and those that are not mutually exclusive. Two events are mutually exclusive if they cannot happen at the same time. In other words, if one event occurs, the other cannot occur. An example of mutually exclusive events is rolling a die and getting a 1 or getting a 2. It’s impossible to roll a 1 and a 2 at the same time.
Two events are independent if the occurrence of one event does not affect the probability of the other event occurring. An example of independent events is flipping two coins and getting two heads. The fact that you got heads on the first flip does not affect the probability of getting heads on the second flip.
Dependent and Independent Events
There are two types of events, dependent and independent. Dependent events are events that depend on each other. This means that the outcome of one event will affect the outcome of another event. For example, if you flipped a coin and it landed on tails, the chance of it landing on tails again is 50%. However, if it landed on heads, the chance of it landing on tails the second time is now 100%. The chance of an event happening has changed based on the outcome of another event.
Independent events areevents that are not affected by each other. This means that the outcome of one event does not have any effect on the outcome of another event. For example, if you flipped a coin and it landed on tails, the chance of it landing on heads the second time is still 50%. The probability has not changed because one event did not affect the other event.
What is the Relationship Between Mutually Exclusive Events and Independence?
Two events are mutually exclusive if they cannot happen at the same time. For example, rolling a die and getting a 1 OR rolling a die and getting a 2. These events cannot happen at the same time, so they are mutually exclusive. Independence, on the other hand, is when the occurrence of one event does not affect the probability of another event. So, are mutually exclusive events independent?
Two Types of Independence
Independence is a fundamental concept in probability that has important applications in real-world situations. Probability is the study of randomness, and independence is a way of quantifying the lack of relationship between two variables.
There are two types of independence: statistical independence and probabilistic independence. Statistical independence occurs when the value of one variable does not affect the value of another variable. For example, the results of a coin flip are independent of the results of a dice roll. Probabilistic independence occurs when the probability of one event does not affect the probability of another event. For example, the probability of getting heads on a coin flip is not affected by whether or not you rolled a 6 on a dice roll.
Mutually exclusive events are two events that cannot happen at the same time. For example, flipping a coin and getting heads is mutually exclusive with flipping a coin and getting tails. Mutually exclusive events are also called disjoint events.
Mutually exclusive events are always statistically independent, but they are not always probabilistically independent. Mutually exclusive events can be probabilistically dependent if their probabilities are not equal. For example, consider two fair coins. The probability of flipping both coins and getting heads is 1/4. The probability of flipping the first coin and getting heads is 1/2, and the probability of flipping the second coin and getting heads is also 1/2. These probabilities are not equal, so the events are probabilistically dependent.
Dependent and Independent Events
Dependent and independent events are two types of events that can occur when two or more items are selected from a population. Mutually exclusive events are a type of dependent event, while non-mutually exclusive events are a type of independent event.
Dependent events are those where the outcome of one event affects the outcome of another event. For example, if you were flipping a coin and the first flip landed on heads, then the second flip would be more likely to land on tails (because there would be less chance of getting two heads in a row). Another example of dependent events would be if you were drawing marbles from a bag – if the first marble you drew was red, then the second marble you drew would be more likely to be a different color (because there would be less chance of getting two red marbles in a row).
Independent events are those where the outcome of one event does not affect the outcome of another event. For example, if you were flipping a coin and the first flip landed on heads, then the second flip would still have an equal chance of landing on either heads or tails (because flipping a coin is random). Another example of independent events would be if you were drawing marbles from two different bags – if the first marble you drew from bag A was red, then the first marble you drew from bag B could still be any color (because each bag has its own set of randomly colored marbles).
Conclusion
After discussing the concepts of mutually exclusive events and independence, we can come to the following conclusion: Mutual exclusivity has no bearing on whether or not two events are independent.
Two events can be mutually exclusive (meaning they cannot happen simultaneously), but still dependent (meaning that the occurrence of one affects the probability of the other). For example, imagine flipping a fair coin. The probability of flipping a Heads is 50%. The probability of flipping a Tails is also 50%. However, the probability of flipping two Heads in a row is only 25% because the first flip affects the outcome of the second flip. In this scenario, the two events are Mutually Exclusive (you cannot have two Heads), but Dependent (the first event affects the probability of the second event).
On the other hand, two events can be Independent (meaning that one event does not affect the probability of another event), but not Mutually Exclusive (meaning that they can happen simultaneously). For example, imagine again flipping a fair coin. The probability of flipping a Heads is 50%. The probability of flipping a Tails is also 50%. The probability of flipping a Heads AND a Tails is still 50% because each flip is independent from each other. In this scenario, the two events are Independent (the first event does not affect the outcome of the second event), but NOT Mutually Exclusive (they can happen together).
