Information was collected on those who attended the opening of a new movie. the analysis found that 56 percent of the moviegoers were female, 26 percent were under age 25, and 17 percent were females under the age of 25. find the probability that a moviegoer is either female or under age 25.

0.65

Step-by-step explanation:

Let A denote that moviegoers were female and B denotes that moviegoers were under age 25.

As per given we have,

P(A)=0.56     P(B)=0.26     P(A∩B)=0.17

Using formula ,

Hence, the probability that a moviegoer is either female or under age 25 = 0.65
