    Exclamation Help with a Probability problem!

    I need some help please? It's a 7th grade probability problem.

    What is the probability that when 2 numbered cubes are thrown that
    at least 1 will land with the number 6 up?

    Thank you very much, for response!

    The total number of outcomes, when 2 cubes are thrown, are (6)(6) = 36

    Number of favorable outcomes are

    (1, 6), (2, 6), (3, 6), (4, 6), (5, 6), (6, 6)

    (6, 1), (6, 2), (6, 3), (6, 4), (6, 5)

    so, 11 outcomes.

    So, Probability = \frac{11}{36}

    "Numbered Cubes"? What a silly question. What are the numbers on the cubes?

    1, 3, 5, 7, 9, 11? Pr(at least one 6) = 0.00

    6, 6, 6, 6, 6, 6? Pr(at least one 6) = 1.00

    I think this is an example of PC Mathematics. Will the use of the word "dice" hurt someones feelings? Oh, no!!! They are teaching my son gambling in school!!

    "Dice" are understood to be cubes with the numbers 1, 2, 3, 4, 5, and 6 on the sides. "Numbered Cubes" are not understood to be anything unless it is defined. Maybe "Numbered Cubes" are understood to be "Dice"?

    I would argue this question if it showed up on my kid's homework.
