Problema Solution
. Essay; show all work. Last fall, a gardener planted 55 iris bulbs. She found that only 45 of the bulbs bloomed 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 of the bulbs should she plant next fall if she would like at least 51 to bloom?

step1 the empirical probability that an iris bulb of this type will bloom. answer as a fraction in lowest terms . = we know emprical probality p= n(s)/n(e)
where n(e)= number of total event
n(s)= number of sample space The first part is 45 / 55 which reduces to 9/11
step2
bulbs should she plant next fall if she would like at least 51 to bloom=
To expect 48, she needs 51 * ( 9/11) = 41.727but since you can't plant a fraction of a bulb, round up to 42
