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?

Last fall, a gardener planted 65 iris bulbs. She found that only 56 of the bulbs bloomed in the spring.?
a) 56/65 = 86.15%


b) 92 * (65/56) = 106.7 or 107
Reply:a) Ratio and percentage of probability:


Ratio:


= 56 to (65 - 56)


= 56 to 9





Percentage:


= 56/65 * 100%


= 1,120/13% or 86 2/13%





b) Bulbs she should plant next fall:


= 92/(56/65)


= 92 * 65/56


= 1,495/14 or 106 11/14


= 107 (approximated)





Answer: She should plant 107 iris bulbs.





Proof:


= 107 * 56/65


= 5,992/65


= 92
