What is the probability that a randomly selected student drives or went to the movies in the past month?

Subtract all three of these probabilities from 1 to find the probability that a person uses neither cream nor sugar, which equals .

What is P(Ac)?

What is the probability that a randomly selected student does not drive?

First, write in the region where the circles overlap.

P(W and F) =

Find P(C and D) =

Suppose we randomly select one of these survey participants. Let C be the event that the participant is an adult. Let D be the event that the participant prefers comedies.What is P(C or D)?

P(C ∩ D) =

Then, to find the probability that a person uses cream but not sugar, and to find the probability that a person uses sugar but not cream.

P(W or F) =

Find P(C or D) =

P(C ∪ D) =

Then, to find the probability that a person uses cream but not sugar, and to find the probability that a person uses sugar but not cream.

P(Fc) =

The probability that a randomly selected participant is an adult prefers comedies is symbolized by P(C ∩ D).

P(Wc and Fc) =
