Explanation / Answer

Total number of possible outcomes = 8

The combinations in which there is exactly 1 boy out of 3 children are ( boy-girl-girl ), (girl-boy-girl) and (girl-girl-boy). So, favourable number of outcomes = 3

Required probability = P(exactly 1 boy out of 3 children) = Number of favourable outcomes / Total number of outcomes = 3 / 8 =0.375
