Question

A bag contains 4 red balls, 3 black balls and 2 blue balls. What is the probabilty that a ball drawn randomly will be black in colour?​

Answer 1

To Find:-

Probability of black balls

Given:-

There are 4 red balls

There are 3 black balls

There are 2 blue balls

Formulae Applied:-

Probability of an event P(E) = No.of outcomes/Total no. of outcomes

Solution:-

Black balls = 3

Total No.of balls = 9

P(black balls) = No.of black balls/Total No.of balls

P(black balls) = 3/9 = 1/3

Therefore,

The probability of black balls is 1/3.

More Information:-

➝ The probability of an event is calculated by the number of outcomes divided by the total number of outcomes.

➝ The probability of possible event is 1.

➝ Probability of impossible event is 0.
