<PRE><B>Question 311699</B>
A box contains 74 brass washers, 86 steel washers and 40 aluminum washers, Three washers are drawn at random from the box without replacement. Determine the probability that all three are steel washers
--------
# of ways to pick 3 steel washers : 86C3 = 102340
---
# of ways to pick 3 randomly: 200C3 = 1313400
--------------
P(pick 3 steel washers) = 86C3/200C3 = 0.0779
