Question

In
cricket match a bats woman hits a
boundary
6 times out of
30 balls she plays.Find
the probability
that
she did not hit a
boundary.

​

Answer 1

Answer- The above question is from the chapter 'Probability'.

Probability- It is the branch of mathematics with deals with the events and tell how likely they occur.

Formula of probability: Favourable outcomes ÷ Total number of outcomes

Given question: In a cricket match a bats-woman hits a boundary 6 times out of 30 balls she plays. Find the probability that she did not hit a boundary.

Solution: Total number of balls = 30

Number of times boundary is hit = 6

Number of times boundary is not hit = Total number of balls - Number of times boundary is hit

Number of times boundary is not hit = 30 - 6 = 24

Here, favourable outcomes i.e. number of times boundary is not hit = 24

total number of outcomes i.e. total number of balls = 30

Required Probability (not hit a boundary) = Favourable outcomes ÷ Total number of outcomes

Required Probability (not hit a boundary) = 24/30

Required Probability (not hit a boundary) = 4/5

∴ Required Probability (not hit a boundary) = $\frac{4}{5}$

Answer 2

Answer:

4/5

✒Explanation

• ✒In a cricket match a batswoman hit a boundary 6 times out of 30 balls she plays.

• Total number of outcomes = 30

• We have to find the probability that she did not hit a boundary.

• Number of favourable outcomes = 30 - 6 = 24 (in which she didn't hit the boundary)

• Now, Probability =

$\pink{\sf{\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}}}</p><p></p><p>$

$\Rightarrow\:\sf{\frac{24}{30}}$

✒On simplifying we get,

$\Rightarrow\:\sf{\frac{4}{5}}$

✒Hence We Are Done !!
