    Question

    If a digit is randomly and evenly distributed among the numbers 0 through 9 then the probability distribution is represented by the following table:

    ——– —— —— —— —— —— —— —— —— —— —— number 0 1 2 3 4 5 6 7 8 9 Odds 1/10 1/10 1/10 1/10 1/10 1/10 1/10 1/10 1/10 1/10 1/10 ——– —— —— —— —— —— —— —— —— —— ——

    We randomly choose a number from the set S = {0,1,2,3,4,5,6,7,8,9}. B is the event that the chosen number is five or greater. The probability of event B is then:


    1. FALSE: 1/10
    2. FALSE: 1/9
    3. FALSE: 1/5
    4. TRUE: 1/2

    1. 1/10: Incorrect
    2. 1/9: Incorrect
    3. 1/5: Incorrect
    4. 1/2: Correct
