Answer 2

Answer :-

Probability of not hitting boundaries = 3/5.

Explanation :-

Given :

• Rohit hit 8 boundaries out of 20 balls.

To Find :

• Probability of not hitting a boundary.

Solution :

Total Balls Faced = 20.

Hitting Boundaries = 8.

Not hitting Boundaries :-

➙ Total Balls – Hitting Boundaries.

➙ 20 – 8.

➙ 12.

And, We know that,

P = Favorable Outcomes/Total Outcomes.

So, Put the values.

➙ P (Not hitting Boundaries) = 12/20.

➙ P (Not hitting Boundaries) = 6/10.

➙ P (Not hitting Boundaries) = 3/5.

Therefore, Probability = 3/5.
