A bag contains 5 red and 3 blue balls. If 3 balls are selected drawn at random without replacement, then the probability of getting exactly one red ball is

A. 15/29

B. 15/56

C. 45/196

D. 135/392

Answer :

Total Red Balls = 5


Total Blue Balls = 3

N = Event getting Blue ball



Now,


P(Getting Exactly one red ball) = P(RBB) + P(BRB) + P(BBR)
