A card is selected at random from a pack of 52 playing cards. The selected card is a queen, the probability of this card to be a card of spade is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $\frac{1}{4}$
No of spade = 13
No. of queen in spade = 1
P(spade queen) = ${^{13}C}_1$
P(total cases) = ${^{52}C}_1$
P(spade queen) = $\frac{{^{13}C}_1}{{^{52}C}_1}=\frac{1}{4}$
