Question 126957: I've tried to answer this question and still can't come up with the answer. Can someone help me? Thanks.

Last fall, a gardener planted 65 iris bulbs. She found that only 56 of the bulbs bloomed in the spring.
a) Find the empirical probability that an iris bulb of this type will bloom
b) How many of the bulbs should she plant next fall if she would like at least 92 to bloom?

"empirical" means observed __ 56 bloomed out of 65 planted __ probability is 56/65

let x="bulbs to plant" __ (56/65)x=92 __ x=92/(56/65)
