Open in App
Solution

There are 4 king, 4 queen and 4 jack in the pack of 52 cards.

Since the cards are drawn with replacement, then there will be 3! possibilities that these cards will occur together.

Also, the probability of occurrence of a king is,

P(king)=452

=d113

The probability of occurrence of a queen is,

P(queen)=452

=113

The probability of occurrence of a jack is,

P(jack)=452

=113

Therefore, the probability of occurrence of a king, a queen and a jack is,

P=3!×113×113×113

=6×12197

=62197
