Question

If P(AUB) =0.80 P(A∩B)=0.15 & P(A)=2P(B) find P(A) & P(B)​

Answer 1

P(An B) + P(AUB) = P(A) + P(B) ------ eq 1

= Now

P(A) = 2 P (B)

To

put ting the value in eq 1

we get

0.15+0.80= P ( A ) + 2P(A)

0.95=3 P (A)

P(A) = 0.95/3

P(A) =0.316 Ans

Now P (A) = 2 P( B )

0.316=2 P (B)

P ( B ) = o.316/2

P(B) = 0.158 Ans
