    A bag contains 15 marbles. Some are red, some are blue and some are green. The probability of choosing a red marble from the bag is 3/5. There is an equal probability of choosing either a blue or green marble. What is the probability of choosing a blue marble following by a red marble?

    Mr. D.

    Dear Dr. Data,
    Do you have any tricks for helping us estimate objects inside of a 3-dimensional object (for instance - how many balls are inside of the jar)?
