I forget absolutely everything having to do with probablility. So, two questions: If two number cubes are rolled, what is the probability that both numbers rolled are even. Annnnnnnndddddddd: If two number cubes are rolled, what is the probability of the sum of the numbers being 5. (6 sided dice, if that wasn't obvious.)

    36 is right; and i usually like to set up a chart for this: 1 2 3 4 5 6 1 2 3 4 5 6 put an "x" in all the combos that sum to 5 and count off the xs

    1 2 3 4 5 6 1 x 2 x 3 x 4 x 5 6 i see 4 out of 36 possible ways

    none of these are combos of even numbers so the answer is 0 out of 36 possibilites for a sum to be 5 AND have 2 even parts
