Question

The following table shows the number of times target was hit by a shooter in a shooting game in each of his 10 games.

Game	No. of times target was hit
first game	1
second game	2
third game	4
fourth game	4
fifth game	7
sixth game	3
seventh game	8
eighth game	8
ninth game	9
tenth game	5

Find the probability that he had exactly hit 8 times.

• A. 0.2

Answer 1

The correct option is A 0.2
Required probability can be obtained by using the formula,

$\text{P(E)}=\frac{\text{Number of trails in which event happened}}{\text{Total number of trials}}$

Total number of games = 10

Out of 10 games played target was hit exactly 8 times in 2 games.

$\therefore$ Required probability

$=\frac{2}{10}$

$=0.20$
