Question

4
A bag contains 3red, 4blue and 5
white balls... A ball is picked at random
What is the probability, that the ball is
1.red?
2.a white
3.a yellow
4.a blue​

Answer 1

Step-by-step explanation:

Total no. of balls = 3 + 4+5

= 12

1.

Red

Total no. Of red ball = 3

So, probability of red balls = 3/12

= 1/4

2.

White

Total no. Of white balls =5

So, probability of white balls = 5/12

3.

Yellow

Total no. Of yellow balls = 0

So, probability of yellow balls = 0/12

=0

4.

Blue

Total no. Of blue balls = 4

So, probability of blue balls = 4/12

= 1/3
