Question 318318: In a large vase are 8 roses, 5 daises, 12 lilies and 9 orchids. If 4 flowers are selected at random, find the probability that at least one of the flowers is a rose.
I started by adding all the flowers and got 34 flowers. I am selecting four flowers so would it be 8/34 X 8/34 X 8/34 X 8/34? I am using the 8 cause its the number of ways to pull a rose and 34 cause its the total number of flowers Answer by scott8148(6628) (Show Source):
