If 5 cards are drawn from a pack, then the probability of selecting the cards of which four of them have same face value is

n(S)=52C5 , it is the number of ways of selecting 5 cards from 52 cards. n(E)=13C1·4C4×48C4 there are 13 sets of face cards, select one set and in that take all four cardsThe probability of selecting the cards of which four of them have same face value is P(E)=13C1×48C152C5
