Answer :

Total numbers of elementary events are: 40

(i) Let E be the event of drawing a card with girl`s name written on it

The numbers of favourable outcomes are: 25

∴ P (girl`s name) = P (E)= 25/40 = 5/8

(ii) Let E be the event of drawing a card with boy`s name written on it

The numbers of favourable outcomes are: 15

∴ P (boy`s name) = P (E) = 15/40 = 3/8
