The probability of getting a white ball from a bag of balls is
1/4.What is the probability of not getting a white ball?
​

Answer 1

The probability of not getting a white ball is: 3/4

Explanation:

Probability is defined as the likeliness of occurrence of an event. The probability is denoted by p.

The sum of probability of occurrence of an event and non-occurrence of an event is 1.

Let p be the probability of getting a white ball

p = 1/4

Let q be the probability of not getting a white ball

q =?

The sum of p and q will be 1.

So,

`p + q = 1\\q = 1-p\\q = 1 - (1)/(4)\\q = (4-1)/(4)\\q = (3)/(4)`

Hence,

The probability of not getting a white ball is: 3/4
