One card is drawn from a pack of 52 cards. What is the probability that the card drawn is either a red card or a king ?
(a)$\frac{1}{2}$
(b)$\frac{6}{13}$
(c)$\frac{7}{13}$
(d)$\frac{27}{52}$
Answer
Answer (as printed): C
Explanation
Here, $n(\mathrm{S})=52$. There are 26 red cards (including 2 kings) and there are 2 more kings. Let $E=$ event of getting a red card or a king. Then, $n(E)=28$. $$\therefore \quad P(E)=\frac{n(E)}{n(S)}=\frac{28}{52}=\frac{7}{13} .$$
