Find the number of 5 card possible hands specified:
a) all red cards
b) all hearts
c) all face cards
d) all kings
a) There are 26 red cards. If we pick one of them 25 remains and so on
So by multiplication rule
Number of 5 cards possible when all of them are red cards = 26*25*24*23*22 = 7893600
b) There are 13 heart cards. If we pick one of them 12 remains and so on
So by multiplication rule
Number of 5 cards possible when all of them are heart cards = 13*12*11*10*9 = 154440
c) There are 12 face cards. If we pick one of them 11 remains and so on
So by multiplication rule
Number of 5 cards possible when all of them are face cards = 12*11*10*9*8 = 95040
b) There are 4 king cards. If we pick one of them 3 remains and so on
So by multiplication rule
Number of 5 cards possible when all of them are heart cards = 4*3*2*1*48 = 1152
(48 because when all kings are picked up there are 48 cards remaining and all of them have equal probablity of picking up)
