Question

Given two independent events A and B such that P(A) = 0.3, P(B) = 0.6 Find
P(A and B)

Answer 1

It is given that P(A) = 0.3 and P(B) = 0.6
Also, A and B are independent events.
$P\left(AorB\right)=P(A\cup B)=P\left(A\right)+P\left(B\right)-P(A\cap B)=P\left(A\right)+P\left(B\right)-P\left(A\right)\times P\left(B\right)=0.3+0.6-0.3\times 0.6=0.9-0.18=0.72$
