Answer:
33/66640=0.0004952
Step-by-step explanation:
A flush is when you have 5 cards of the same suit.
There are 13 cards of each suit and total 52 cards
probability of drawing first card=13/52
probability of drawing second card=12/51
probability of drawing third card=11/50
probability of drawing fourth card=10/49
probability of drawing fifth card=9/48
Hence, total probability=
(13×12×11×10×9)/(52×51×50×49×48)
= 33/66640
=0.0004952
