Question

A bag contains 5 red alls, 7 black balls and 8 green balls. A ball is drawn randomly from the bag, the probability of getting a green ball is $\frac{2}{m}$, then Value of m is

Answer 1

No. of green balls $=8$

Total number of balls or total outcomes $=5+7+8=20$

Probability of getting a green ball = $\frac{8}{20}=\frac{2}{5}=\frac{2}{m}$

by comparing $m=5$
