Probability of A and B |
If A and B are independent events, then P(A andB)=P(A) * P(B). |
P(A)= 50 %, P(B)= 25 %

A compound event is an event that is made up of two or more events. In our exercise, the events A and B were independent. To find the probability that two independent events will occur, we can multiply the probabilities of each event, as we did in our solution.
Probability of A and B |
If A and B are independent events, then P(A andB)=P(A) * P(B). |
Events that cannot happen at the same time are called mutually exclusive events. The following rule tells us about the probability of mutually exclusive events.
Probability of Mutually Exclusive Events |
If A and B are mutually exclusive events, then P(A andB)=0, and P(A or B) = P(A) + P(B). |
Sometimes, the events can be overlapping. Overlapping events have outcomes in common. Recall the rule that tells us about the probability of such events.
Probability of Overlapping Events |
If A and B are overlapping exclusive events, then P(A or B) = P(A) + P(B) - P(A and B). |
