If a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5 then the probability of getting red balls is 3/10.
Given that a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5.
We are required to find the probability of getting red balls.
Probability=Number of items/Total items
Probability of getting red balls=1-(Probability of getting white balls +Probability of getting black balls)
=1-(3/10+2/5)
=1-7/10
=3/10
Hence if a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5 then the probability of getting red balls is 3/10.
