Answer 1

Question -

Reena withdraws white ball from a bag of 4 white balls find the probability of getting a white ball

Answer -

Given : There are total 4 white balls in a bag and one white ball is drawn what is the probability of getting white ball .

To find : The probability of getting a white ball

Concept insight : It is stated that the bag contains 4 white balls so the bag has only white balls no matter how many times we withdraw a ball the outcome will be a white ball only

Solution :

Number of total outcomes = 4

Number of favorable outcomes = 4

Probability = $\dfrac{Favourable\: outcomes}{Total\: outcomes}$

Probability of getting a white ball is = $\dfrac{4}{4}$

$\mapsto\:\dfrac{\not{4}}{\not{4}}$

= 1

Hence , the probability of getting a white ball is one

Thus , Option c is correct .
