Question

In a cricket match a bastwomen hits a boundary 5timesand 30balls she plays .find the probability that she did not hit a boundary

Answer 1

Answer:

5/6

Step-by-step explanation:

If the batswomen hits 5 boundaries in 30 balls,

She will not hit boundaries in the rest 25 balls

Probability =no. Of favourable outcomes/total no. Of outcomes

Probability(not hitting a boundary) = 25/30

= 5/6

The probability of the batswomen not hitting a boundary is 5/6

Step - By - Step Explanation :

Given :

• Ball hits boundary = 5 times
• Total ball she plays = 30

To Find :

• The probability that it didn't hit the boundary.

SolUtion :

First of all, find the number of times the ball did't hit boundary.

$\sf ball\:didn't\:hit\:boundary= 30 - 5$

$\sf = 25\:times$

Also,

$\sf Probability =\dfrac{Outcomes\:occurs}{Total\:Outcomes}$

$\sf\implies Probability =\dfrac{25}{30}$

$\sf\therefore Probability = \dfrac{5}{6}$

Hence,

The probability that she didn't hit the boundary is 5 : 6
