Question

One card is drawn from a well shuffled pack of 52 cards.Find the probability of getting :

(ii) a spade.

Answer 1

Total number of cards = 52
∴ n (S) = 52
Now,
Let B be the event of getting a spade.
We know:
Number of spades = 13
$\therefore$ n (B) = 13
And,
P (B) = $\frac{n\left(B\right)}{n\left(S\right)}=\frac{13}{52}=\frac{1}{4}$
$\therefore$ Probability of getting a spade = $\frac{1}{4}$
