Answer 2

Answer:

4/5

Explanation:

Given:

Ball played = 30 times.

Times it hits the boundary = 6 times.

To Find:

• Probability of the times it did not hit the boundary.

Formula Used:

$probablity = \sf \: \dfrac{ Number \: \: \: of \: \: \: balls \: \: \: on \: \: \: not \: \: \: hitting \: \: \: the \: \: \: boundary. }{Total \: \: \: number \: \: \: of \: \: \: balls \: \: \: played}$

Procedure:

• Finding Number of times when it did not hit the boundary:

→ Number of times when it did not hit the boundary = Total number of balls - Number of times when it did not hit.

→ Number of times when it did not hit the boundary = 30 - 6

→ Number of times when it did not hit the boundary = 24

• Finding probability:-

$\sf \implies p(did \: not \: hit \: boundary) = \dfrac{balls \: did \: not \: hit}{total \: number \: of \: balls \: played}$

$\sf \implies p(did \: not \: hit \: boundary) = \dfrac{24}{30}$

$\sf \implies p(did \: not \: hit \: boundary) = \dfrac{4}{5}$

• Probability : Probability is the uncertainty of occuring or happening of something

• Its widely used in every field such as physical sciences , commerce , biological sciences , medical sciences , weather forecasting.

• Emperical Approach : An operation which can produce some well defined outcomes.
