Question

The tree diagram represents an experiment consisting of two trials.

Answer 1

Answer:

P(D) = 0.65

Step-by-step explanation:

it's like following a path on map

each line is like a street length

First, it's 0.5 to A and then 0.6 to D.

Then, it's 0.5 to B and 0.7 to D.

P(D) = (0.5 times 0.6) + (0.5 times 0.7) =

P(D) = 0.30 + 0.35 = 0.65
