Take
two boxes of different flavored goldfish crackers and
a large paper bag.
- Pour one flavor of goldfish crackers into the paper
bag.
- Remove a large handful of crackers from the bag and
count them. Replace the crackers taken out with the
same number of a different flavored cracker. Mix well.
- Remove another large handful of crackers from the
bag. Record the total number of crackers in this handful
and the number of these that are of the second flavor.
- Use the method in the challenge to estimate the total
number of crackers in the bag.
- Replace the handful of crackers in step three. Mix
well. Repeat steps three and four to get 5 estimates
in all.
- Find the average of the 5 estimates.
- How does the average compare to the total number
of crackers in the bag?
