Using the concept of combination, since the order of selection doesn't matter, the number of ways in which four 8's can be chosen is 1

There are 13 cards in a suit :

Number of cards numbered 8 in a suit = 1

Number of ways of choosing a specific card :

(13C1) ÷ 13 = (13 ÷ 13) = 1 way

Since there are four different suits :

The number of ways of selecting a card numbered 8 from 3 each suit will be 1.

Hence, the number of ways in which four 8's can be chosen would be :

  • 1 × 1 × 1 × 1 = 1

Therefore, there is only 1 way of choosing four 8's
