step 1 go next door to the grocery store ( you
said to use my imagination, and in MY
imagination, there IS a grocery store next door)
step 2 compare the size of the jelly beans to
that of dried beans at the store. Select and
purchase the beans that are closest. (dried
beans are much cheaper than jelly beans, so this
is a worthwhile investment if it gets you closer
to winning the large jar of jelly beans.) step
3 bring the bag of dried beans back to the candy
store, and fill the empty jar. step 4 empty the
jar of beans into a separate bag from the
leftover beans. step 5 bring this bag into the
bathroom of the candy store and count them. This
will ensure that no one counts over your
shoulder and steals your answer. step 6 submit
your answer and await your prize!!!

• Suppose your have a jar of 1000 jelly beans and
  that there are only three different colors of
  jelly beans inside red, blue, and yellow.
  Suppose you reach into the jar and randomly pull
  out one jelly bean at a time without looking,
  placing the bean on the desk in front of you.
• How many beans do you need to pull out until
  you are guaranteed to have at least two of the
  same color on the desk in front of you?
