Question

A card is drawn at random from a pack of well shuffled $52$ playing cards find the probability that the card draw is
i) an ace
ii) a spade

Answer 1

Total number of cards $T=52$

Total number of aces in cards $A=4$

Total number of spades $S=13$

Probability that the card drawn is an ace$=\frac{A}{T}=\frac{4}{52}=\frac{1}{13}$

Probability that the card drawn is a spade$=\frac{S}{T}=\frac{13}{52}=\frac{1}{4}$
