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
