Question

a bag contains 12 red 10 blue 21 green and 7 white balls what is the probability of taking out a blue ball

Answer 1

Given:

A bag contains 12 red 10 blue 21 green and 7 white balls.

To find:

probability of taking out a blue ball.

Solution:

1) Probability is the possibility of an event which is about to happen.

2) probability of an event is given by;

• P(E)= number of outcomes/ total number of outcomes

3) Total number of balls are 12+10+21+7 = 50 and Number of blue balls are 10

• P(E)= number of blue balls/ total number of balls

• P(E)= 10/50

• P(E)=1/5

Probability of taking out a blue ball is 1/5.
