State whether the statements in True or False.

There will be only 24 selections containing at least one red ball out of a bag containing 4 red and 5 black balls. It is being given that the balls of the same colour are identical.

Answers (1)

False.

Number of ways of selecting any number of objects from n given identical objects is 1. Now, selecting 0 or more red ball from 4 identical red balls= 1+1+1+1+1=5

Selecting at least 1 black ball from 5 identical black balls =1+1+1+1+1=5

So, total ways=5*5 =25
