A deck of 52 cards is mixed well, and 5 cards are dealt.

(a) It can be shown that (disregarding the order in which the cards are dealt) there are 2,598,960 possible hands, of which only 1287 are hands consisting entirely ofdiamonds.
What is the probability that a hand will consist entirely of diamonds? (Give the answer to six decimal places.)


What is the probability that a hand will consist entirely of a single suit? (Give the answer to six decimal places.)


(b) It can be shown that exactly 63,206 hands contain only clubs and hearts, with both suits represented.
What is the probability that a hand consists entirely of clubs and hearts with both suits represented? (Give the answer to five decimal places.)


(c) Using the result of Part (b), what is the probability that a hand contains cards from exactly two suits? (Give the answer to five decimal places.)

Solution

probability that a hand will consist entirely of diamonds = 1287/ 2,598,960

=0.000495

the probability that a hand will consist entirely of a single suit

= 4(0.000495) =0.001981

the probability that a hand consists entirely of clubs and hearts with both suits represented

= 63206/2,598,960

=0.02432

c) the probability that a hand contains cards from exactly two suits? (Give the answer to five decimal places.)

= 2(0.02432)

= 0.04864
