Question

If P(A) = 0.60 and P(B) = 0.20, then A and B are independent events ifA. P(A or B) = 0.12B. P(A or B) = 0.80C. P(A and B) = 0D. P(A and B) = 0.12

Answer 1

Explanation

When two events are independent

$\begin{gathered} P(A\cap B)=P(A)\times P(B) \\ \end{gathered}$

If P(A) = 0.60 and P(B) = 0.20, therefore;

$P\left(A\text{ }and\text{ }B\right)=0.12$
