Question

Dependent Event

P(B)=0.70

P(B')=0.30

P(A and B)=0.63

P(A l B) = 0.90

0.36 of set is neither A nor B

Find P(A' l B')

Answer #1

Hey there stay home and stay safe

$\small P(B)=0.70\\ P(B')=0.30\\ P(A\cap B)=0.63\\ P(A' \cap B')=0.36\\ P(A'|B')\\ =\frac{P(A' \cap B')}{P(B')}\\ =\frac{0.36}{0.30}\\ =0.12$
