Question 103736
Three roses are to be placed in a vase. the color choices are red,pink,white,yellow, and orange. what is the probability that 3 roses selected at random will not include red? 
----------------------
# of ways to pick three roses that are not red = 4C3 = 4
# of ways to pick three roses of any color = 5C3 = 10
--------------
P(pick three that are not red) = 4/10 = 0.4
