A card is drawn at random from a pack of 52 cards. The probability that the drawn card is not a king is:

A) \[\frac{1}{13}\]

B) \[\frac{9}{13}\]

C) \[\frac{4}{13}\]

D) \[\frac{12}{13}\]

Correct Answer: D

Solution :

[d] Total number of possible outcomes = 52

Number of king cards in the pack =4

\[\therefore \]Number of cards that are not king\[=52-4=48\]

So, favourable number of outcomes =48

\[\therefore \] Required probability \[=\frac{48}{52}=\frac{12}{13}\]
