Question

A box contains 7 blue balls,2 red balls and 1 green ball, if a ball is picked at random, find the probability that the ball will be (i)red ball (ii) green ball. with working

Answer 1

Blue=7

Red=2

Green=1

Total Balls:10.

P (Red Ball)= Favorable outcomes /

                      Total Outcomes.

=2/10 = 1/5

P(Green)= 1/10.

Therefore answer is 1/5 and 1/10.

Answer 2

Answer:

I)1/5. ll)1/10

Step-by-step explanation:

because to find probability find total number of objects and then using fractional format write probability.

structure

number of red ball/total no. of balls in the box

and then reduce it to lowest form
