$\frac{{24}}{{64}}$
$\frac{{40}}{{64}}$
$\frac{{49}}{{64}}$
$\frac{{64}}{{64}}$
From a pack of $52$ cards two are drawn with replacement. The probability, that the first is a diamond and the second is a king, is
The probability of hitting a target by three marksmen are $\frac{1}{2},\,\frac{1}{3}$ and $\frac{1}{4}$ respectively. The probability that one and only one of them will hit the target when they fire simultaneously, is
Two integers $\mathrm{x}$ and $\mathrm{y}$ are chosen with replacement from the set $\{0,1,2,3, \ldots ., 10\}$. Then the probability that $|x-y|>5$ is:
Three coins are tossed. Describe Two events which are mutually exclusive but not exhaustive.
A die has two faces each with number $^{\prime}1^{\prime}$ , three faces each with number $^{\prime}2^{\prime}$ and one face with number $^{\prime}3^{\prime}$. If die is rolled once, determine $P(1$ or $3)$
