28. Our medicine supplies come in boxes that are (S)mall, (M)edium, (L)arge.

Small boxes are ordered 25% of the time and are damaged (D) 2% of the time.

Medium boxes are ordered 35% of the time and are damaged ( D) 5% of the time.

Large boxes are ordered 40% of the time and are damaged 3% (D) of the time.

Given this information, what are the following probabilities?

I understand how to get the answers but I have to draw a decision tree and I am not sure how.

D S = .005

D M = .0175

D L = .012 S AND D = .00125

M AND D= .006125

L AND D = .0048

D = .01085

S D = .25

M D = .35

L D = .4
