Five cards are dealt from a standard 52 card deck
a)
Total cards = 52
number of possible outcomes of selecting 5 cards = 52C5 =
2598960
b-a)
so, total possible ways of flush = 13C5*4 = 5148
So, P(Flush) = 5148/2598960=0.001980792
b-b)
Four of a kind- 4 cards of one denomination and one
card of a second denomination.
there is 13 possible cases of one denomination
second denomination means 12 possible cases will occur
from 12 cases either 1 from a set (4 suit)
total number of ways =13C1*12C1*4C1 = 624
P(four of a kind) = 624/2598960=
0.000240096
