What is the formula for finding the probability of the union of two events?

Back

P(A or B) = P(A) + P(B) - P(A and B), where A and B are two events.

What does it mean for events to be mutually exclusive?

Back

Two events are mutually exclusive if they cannot occur at the same time.

Front

How do you interpret the results of a Venn diagram?

Back

The areas of overlap in a Venn diagram represent the intersection of sets, while the individual areas represent unique elements of each set.

Front

What is the probability of selecting a student who plays soccer from a survey of 110 students?

Back

To find this probability, divide the number of students who play soccer by the total number of students surveyed.
