Question

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.
How many of the bulbs should she plant next fall if she would like at least 60 to bloom?

Answer 1

empirical probability : 58/68 = .85

she should plant:
.85 = 60/totalPlant
totalPlant ~ 70
