Question

If PA. = 0.8, PB. = 0.3 and P(A|B) = 0.6, what is P(A and B)

Answer 1

Answer:

p(A∩B) = 0.18

Step-by-step explanation:

Formula :

$p\left( A|B\right) =\frac{p\left( A\cap B\right) }{p\left( B\right) }$

………………………………

⇒ p(A∩B) = p(B)×p(A/B)

⇒ p(A∩B) = 0.3 × 0.6

                = 0.18
