    Answer: a. 1/6. b. 2/3. c. 5/6

    Step-by-step explanation:

    Number of adults randomly selected = 6

    a. Finding the probability of adults that have cheated on an examination before is exactly 4.

    The numbers are 1, 2, 3, 4, 5 and 6.

    Probability of chosen exactly 4 will be 1/6 since 4 can only occur once.

    b. More than 2means 3,4, 5 and 6.

    Probability that the number of adults that have cheated on a test or exam is more than 2 will be:

    4/6 = 2/3

    c. At most 5 means 1,2,3,4 or 5

    This will give 5/6
