For two events A and B , P(A)=0.41 and P(B)=0.25.

Question

Which of the following could be the value of P(A∨B)?

Answer Choices

0.7

0.65

0.9

0.81

Answer 1

Assuming events are independent,

Prob ( A or B) = Prob(A)+ Prob(B) = 0.41 + 0.25 = 0.66

Otherwise, we need Prob ( A and B) and

Prob (A or B) = Prob(A) + Prob(B) - Prob (A and B)

0.65 i the closest answer...
