Question

Given P(A) = 0.56, P(B) = 0.45 and P(B|A) = 0.7, find the value of

Answer 1

Answer:

P(A and B) = P(AnB)

Step-by-step explanation:

$P( \frac{A}{B} ) = \frac{P(AnB)}{P(B)} \\from \: bayes \: theorem \\ P(AnB) = P(B) \times P( \frac{A}{B}) \\ = 0.45 \times 0.7 \\ = 0.315$

Answer 2

Answer: 0.392

Step-by-step explanation:

So P(A)xP(B|A)= P(AnB)

Plug in

0.56x0.7=0.392
