Question 465368
given a regular 52- card deck, what is the probability of getting a 5-card hand with at least one heart? 
---
P(at least one heart) = 1 - P(no heart)
= 1 - [39C5/52C5] 
---
= 1 - [0.2215]
---
= 0.7785
===========================

and what is the probabilty of getting a 5-card hand that consists of 3 red cards and 2 black cards?
---
P(3red and 2 black) 
= [26C3*26C2]/[52C5] 
= 0.3251
==============
