1. 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. $\frac{27}{52}$

Solution:

Here, n(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

∴ P (E) = \frac{n (E)}{n (S)} = \frac{28}{52} = \frac{7}{13}
