Let A and B be disjoint events and assume that Pr(A) = Pr(B) and Pr(AUB) = 0.8. Then Pr(A) =
Select one:
a. 0.4
b. 0.1
c. 0.2
d. 0.3
If two events “A” and “B” are disjoint, then
“Pr(A cup B) = Pr(A) + Pr(B).”
Hence
“Pr(A)=Pr(A cup B)- Pr(B)”
Given “Pr(A)=Pr(B)”
“Pr(A)=Pr(A cup B)- Pr(A)”
“Pr(A)=0.5Pr(A cup B)”
“Pr(A)=0.5(0.8)=0.4”
a. 0.4
