The tree diagram represents an experiment consisting of two trials. P(D)=? Please help!!!

P(D) = 0.65

Step-by-step explanation:

Follow the segments that lead to D.

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 * 0.6 + 0.5 * 0.7 = 0.3 + 0.35 = 0.65

P(D) = 0.65

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
