<PRE><B>Question 838634</B>
A BAG CONTAIN 3 RED, 2 GREEN, 5 BLUE, AND 2 YELLOW BALLS. FIND THE PROBABILITY THAT BALLS OF ALL THE COLORS ARE REPRESENTED IF A SAMPLE OF FOUR BALLS IS SELECTED AT RANDOM?
------
# of ways to succeed: 3*2*5*2 = 60
# of quadruples:: 12C4 = 495
-----
P(all colors) = 60/495 = 0.1212
