A card is drawn one at a time from a
well-shuffled deck of 52 cards. In 13
repetitions of this experiment, 2 kings
are drawn. If E is the event in which
a king is drawn in the 13 trials, find
the experimental probability P(E).
P(E) =

Answer:

[tex]= \frac{6}{55}[/tex]

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

= [tex]^{13}C_4[/tex]

In 13 repetition, 2 kings are drawn by [tex]^{13}C_2[/tex] way

Now,

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

[tex]= \frac{13 !}{11 !\ 2 !} / \frac{13 !}{9 !\ 4 !}[/tex]

[tex]= \frac{9 !\ 4 !}{11 !\ 2!}[/tex]

[tex]= \frac{4\times 3}{11\times 10}[/tex]

[tex]= \frac{6}{55}[/tex]

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