Question

Four cards are drawn at a time from a pack of 52 playing cards. Find the probability of getting all the four cards of the same suit.

Answer 1

Answer:

Step-by-step explanation:

Four cards can be selected from 52 cards in 52C4ways.

Now, there are four suits, e.g. club, spade, heart and diamond each of 13 cards.

So total number of ways of getting all the four cards of the same suit:

⇒ 13C4+13C4+13C4+13C4 = 4×13C4

So required probability =

4×13C4/52C4

= 198/20825
