Question

A card is drawn one at a time from a

Answer 1

Answer:

$= \frac{6}{55}$

Step-by-step explanation:

The computation of experimental probability is shown below:-

The Number of king in a well shuffled deck consists 52 cards which is

= 4

The Number of ways of drawing consists of 4 king in 13 repetitions which is

= $^{13}C_4$

In 13 repetition, 2 kings are drawn by $^{13}C_2$ way

Now,

$P(E) = \frac{^{13}C_2}{^{13}C_4} = \frac{13 !} {(13-2) ! } / \frac{13 !}{(13 - 4)! 4!}$

$= \frac{13 !}{11 !\ 2 !} / \frac{13 !}{9 !\ 4 !}$

$= \frac{9 !\ 4 !}{11 !\ 2!}$

$= \frac{4\times 3}{11\times 10}$

$= \frac{6}{55}$

Therefore for computing the experimental probability we simply applied the above formula.
