From a pack of $52$ cards one card is drawn at random, the probability that it is either a king or a queen is

A

$\frac{1}{{13}}$

B

$\frac{2}{{13}}$

C

$\frac{3}{{13}}$

D

$\frac{4}{{13}}$

Solution

(b) Probability of getting king $ = \frac{4}{{52}} = \frac{1}{{13}}$

Probability of getting queen $ = \frac{4}{{52}} = \frac{1}{{13}}$

$P$ (king or queen) $ = \frac{1}{{13}} + \frac{1}{{13}} = \frac{2}{{13}}.$
