You can put this solution on YOUR website! In a large vase, there are 8 roses, 5 daisies, 12 lilies, and 9 orchids. If 4 flowers are selected at random, find the probability that at least 1 of the flowers is a rose.
-------------
P(at least one rose in picking 4) = 1 - P(no rose in picking 4)
= 1 - [26C4/34C4]
---
= 1 - 0.3224
---
= 0.6776
