Question
A card is drawn from a pack of 52 cards. The probability of getting a queen of club or a king of heart is:
Answer: Option C
Here, n(S) = 52
Let E = event of getting a queen of club or a king of heart
Then, n(E) = 2
$$\eqalign{
& \therefore P\left( E \right) = \frac{{n\left( E \right)}}{{n\left( S \right)}} \cr
& = \frac{2}{{52}} \cr
& = \frac{1}{{26}} \cr} $$
