A card is drawn from a well shuffled pack of cards. The probability of getting a queen of club or king of heart is

A

152\frac { 1 } { 52 }

B

126\frac { 1 } { 26 }

C

118\frac { 1 } { 18 }

D

None of these

Answer

126\frac { 1 } { 26 }

Explanation

Solution

The probability of card to be queen of club is 152\frac { 1 } { 52 }

and also probability of card to be a king of heart is 152\frac { 1 } { 52 }.

Both are mutually exclusive events, hence the required probability=152+152=252=126= \frac { 1 } { 52 } + \frac { 1 } { 52 } = \frac { 2 } { 52 } = \frac { 1 } { 26 }.
