A bin contains 100 balls, of which 25 are red, 40 are while and 35 are black. If two balls are selected from the bin without replacement, What is the probability that one will be red and one will be white?
------
# of ways to succeed: 25*40 = 1000
# of possible pairs: 100C2 = 4950
----
P(one red and one white) = 1000/4950 = 0.2020
