<PRE><B>Question 415661</B>
if jane has 100 marbles. 25 white marbles and 35 red ones and the rest blue. 
If she randomly picks a marble from the bag, what is the probability that the marbles wont be red or white?
--------------------------
If it is not red or blue it must be white.
----
P(not red or blue) = P(white) = 25/100 = 1/4
