Question

The tree diagram represents an experiment consisting two trials

Answer 1

0.35

Step-by-step explanation:

To find the probability of a sequence of events, multiply along the branches representing those events.

Therefore, P(B and D) = 0.5 x 0.7 = 0.35

** refer to the attached diagram **

Answer 2

0.35

Step-by-step explanation:

• P ( B and D )

• 0.5 * 0.7

• 0.35

Follow the branch B and then branch D

• multiply both the selected probabilities to calculate total probability.
