Question 383478: Essay; show all work. Last fall, a gardener planted 68 iris bulbs. She found that only 58 of the bulbs bloomed in the spring.

Find the empirical probability that an iris bulb of this type will bloom. Give answer as a fraction in lowest terms.
How many of the bulbs should she plant next fall if she would like at least 60 to bloom?

Empirical probability that an iris bulb of this type will bloom = 58/68, or 29/34.
Now 29%2F34+=+60%2Fx, or x = 34*60/29 = 70.345. Therefore, she has to plant 70 for at least 60 to bloom.
