The Family has three children.

each child can be either a boy or a girl.

So total outcomes = 2^3 = 8

[ The 8 Outcomes are {BBB, BBG, BGB, GBB, BGG, GBG, GGB, GGG} ]

i) Exactly one girl = {GBB, BGB, BBG}

favourable out comes = 3

Probability = 3/8

ii) Atleast one girl (means minimum 1 girl; it can be 1, 2 or 3) = {BBG, BGB, GBB, BGG, GBG, GGB, GGG}

favourable out comes = 7

probability = 7/8

iii) Atmost one girl (means number of girls cam be 0 or 1) = {BBB, BBG, BGB, GBB}

favourable out comes = 4

probability = 4/8 = 1/2

2. Atleast one boy (means minimum 1 boy; it can be 1, 2 or 3) = {BBB, BBG, BGB, GBB, BGG, GBG, GGB}

favourable out comes = 7

probability = 7/8
