Question

Sharon is planting tulip

bulbs in her garden. In the
catalog she sees a disclaimer that there is a 1/15 probability that a bulb will not flower. If Sharon plants 90 bulbs, how many tulips can she expect to see in her garden?

Answer 1

84 flowers.

Explanation:

We must multiply 90 by 1/15 to get 6 bulbs that will not flower. 90-6 is 84.
