Last fall, a gardener planted 56 iris bulbs. She found that only 49 of the bulbs bllomed 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 bulbs should she plant next fall if she would like at least 52 to bloom?
49/56 = 7/8
If you plant X and expect 52 to bloom,
(7/8)X = 52
X = 59.4, so plant 60.
