Last fall, a gardener planted 64 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. Give answer as a fraction in lowest terms.
b.) How many of the bulbs should she plant next fall if she would like at least 59 to bloom?

  • MATH-too confusing :( - , Friday, July 22, 2011 at 1:02pm

    Pr(bloom)=56/64

    59=N*pr(bloom) solve for N

    If I were her, I would double N and add 20 to get at least 59 :) Iris bulbs are not my favorite bloomer.
