Question

In a cricket match,a batsmen hits a boundary 6 times out of 30 balls he played.Find the probability that he did not hit a boundary.

I will mark you as you wish....

Answer 1

number of balls = 30

number of times boundary hit = 6

probability of boundaries = 6 / 30 = 1/5

there fore probability of boundaries not hit = 5/5 - 1/5 = 4/5

Answer 2

Given :

• Total Balls is 30 .
• She hits the boundary 6 times .

To Find :

• Probability that she didi not hit a boundary .

Solution :

$\longmapsto\tt{Total\:Balls=30}$

$\longmapsto\tt{Hits\:a\:boundary=6\:times}$

$\longmapsto\tt{She\:did\:not\:hit=30-6}$

$\longmapsto\tt\bf{24\:times}$

Now ,

$\longmapsto\tt{Probability=\frac{No.\:of\:Fav.\:Outcomes}{Total\:No.\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{24}{30}}$

$\longmapsto\tt\bf{\dfrac{4}{5}}$

So , The Probability that she did not hit the boundary is 4/5 ...

• Probability of an event can never be negative.
• Probability of an event always lies between 0 and 1.
