  • Math -

    There are 36 possibilities with two dice. Either-or probabilities are found by adding the individual probabilities.

    1. A sum of seven can be gotten with 2,5; 5,2; 3,4; 4,3; 6,1; or 1,6. That is 6/36 = 1/6

    2. Sum greater than three = 1 - sum of 3 or less. Go through the same process.

    3. Go through a similar process.

    b. Subtract previous answers from 1, except for 2.
