In a large vase, there are 8 roses, 5 daisies, 12 lilies and 9 orchids. If 3 flowers are selected at random, find the probability that at least 1 of the flowers is a lily.
Assuming that the events are dependent. Would you consider this event likely to
occur? Explain your answer.
Can someone show me the calculation. the ans is 0.7426
what is the chance that no flower is a lily?
22/34 * 21/33 * 20/32 = 0.2574
Now subtract that from 1 and you have your answer
