let a and b be two events with the following probabilities.\n- p(a) = 0.5\n- p(b) = 0.2\n- p(a and b) = 0.1\ncomplete the sentence.\nsince p(a and b) equal to p(a)·p(b), events a and b must independent.
Answer
Explanation:
Step1: Calculate $P(A)\cdot P(B)$
$P(A)\cdot P(B)=0.5\times0.2 = 0.1$
Step2: Compare with $P(A\ and\ B)$
We know $P(A\ and\ B)=0.1$. Since $P(A)\cdot P(B)=0.1$ and $P(A\ and\ B) = 0.1$, we have $P(A\ and\ B)=P(A)\cdot P(B)$.
