Answer 1

0.12

Explanation:

Given the frequencies of occurrence in the diagram, you want to know the probability of A and B.

Probability

The probability of an event is the ratio of the number of times it occurs to the total number of trials.

The diagram shows the event (A and B) occurs 6 times out of a total of 6+6+20+20 = 52 trials.

P(A and B) = 6/52

P(A and B) ≈ 0.12
