Answer

The statement "Two independent events cannot occur at the same time" is false.

Solution

1. Two independent events are defined such that the occurrence of one does not affect the probability of the occurrence of the other. This does not mean that they cannot occur simultaneously. For example, in tossing a coin twice, getting heads on the first toss and heads on the second toss are independent events, and they can occur at the same time in a single experiment. 2. Two disjoint (mutually exclusive) events have no outcomes in common. By definition, they cannot occur at the same time since their intersection is empty. 3. Two complementary events are a specific case of disjoint events where the events cover the entire sample space. They also cannot occur simultaneously. Thus, the false statement is: \( \text{"Two independent events cannot occur at the same time."} \)

Did you know that independent events are the life of the party? They can totally happen simultaneously! For example, flipping a coin and rolling a die are independent events – the outcome of one doesn’t affect the other. So, saying they can’t occur at the same time is definitely false! On the other hand, disjoint events are like oil and water – they just don't mix! If two events are disjoint, known as mutually exclusive, they cannot happen at the same time. For instance, rolling a 3 or a 4 on a single die can’t happen simultaneously. So, keep that in mind when you're making your probabilities calculations!
