`S={"HHH, HHT, HTH, THH, HTT, THT, TTH, TTT"}.`
`thereforen(S)=8.`
Condition for event A : To get at least two heads.
`thereforeA={HHH,HHT,HTH,THH}" "thereforen(A)=4.`

Condition for event B : To get no head.
`thereforeB={"TTT"}" "thereforen(B)=1.`
Conditions for event C : To get head on the second coin.
