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
Ans: 56/65 = 0.8615
--------------------------------------
b) How many of the bulbs should she plant next fall if she would like at least 92 to bloom?
Let the desired number be "x"
Equation:
(56/65)x >= 92
x >= (65/56)(92)
x >= 106.79
Rounding up
x >= 107
