Question

A tree diagram represents an experiment consisting of two trails.

P(A and D) = [?]

Answer 1

0.3

Explanation:

Start at the beginning, follow the branch to A and then the branch to D (see attached annotated diagram).

When calculating the probability of an event AND another event, multiply the probabilities.

P(A and D) = 0.5 x 0.6 = 0.3
