If A and B are two independent events such that P(A) = 2/7 and P(B) = 1/6 then P(A’ ∩ B’) is _________ |
2/42 25/42 25/49 5/42 |
25/42 |
$P(A)=\frac{2}{7},P(B)=\frac{1}{6}$ $P(A')=1-\frac{2}{7}=\frac{5}{7},P(B')=1-\frac{1}{6}=\frac{5}{6}$ $P(A'∩B')=P(A')×P(B')$ [Independent] $=\frac{5}{7}×\frac{5}{6}=\frac{25}{42}$ |
