From a pack of 52 cards, one card is drawn at random. What is the probability that the card drawn is a ten or a spade ?
(a)$\frac{4}{13}$
(b)$\frac{1}{4}$
(c)$\frac{1}{13}$
(d)$\frac{1}{26}$
Answer
Answer (as printed): A
Explanation
Here, $n(\mathrm{S})=52$. There are 13 spades (including one ten) and there are 3 more tens. Let $E=$ event of getting a ten or a spade. Then, $n(E)=(13+3)=16$. $$\therefore \quad P(E)=\frac{n(E)}{n(S)}=\frac{16}{52}=\frac{4}{13} .$$
