Question

Sally got shot by some purp(s). She could have been shot by Adam (A) or Billy (B) or both, but those are the only possibilities. Pr(A) - 0.34 and Pr(B) - 0.72. The sample space can represented as: А Б В a. Compute Pr(AUB): b. Compute Pr(): c. Compute PrAnB): d. Compute Pr(AB): e. Compute Pr(BIA):

Answer 1

from given diagram":

a. Compute Pr(AUB): 1 b. Compute Pro): 1 C. Compute Pr(AnB): 0.34+0.72-1=0.06 d. Compute P(AB): 0.06/0.72=0.0833 e. Compute Pr(BIA): 0.06/0.34=0.1765
