    Question

    Two balanced dice are rolled. Define the stochastic variable X is the sum of the eyes that come up, so we have the following probability with different values of X:

    ——– —— — —- — —— — — — —- —- —— X 2 3 43 5 6 7 8 9 10 11 12 Odds 1/36 ? ? ? 5/36 ? ? ? ? ? 1/36 ——– —— — —- — —— — — — —- —- ——

    Then what is the probability of X = 8?


    1. FALSE: 3/36
    2. FALSE: 4/36
    3. TRUE: 5/36
    4. FALSE: 6/36

    1. 3/36: Incorrect
    2. 4/36: Incorrect
    3. 5/36: Correct
    4. 6/36: Incorrect
