<PRE><B>Question 852463</B>
5 marbles are drawn from a hat containing 6 white marbles and 4 black marbles.
Find the probability that at least 3 of the 5 marbles are white.
------
# of ways to succeed: 6C3*4C2 + 6C4*4C1 + 6C5 = 186
# of ways to randomly seclect 5 marbles: 10C5 = 252
----
P(condition) = 186/252 = 0.7381
