    Answer:

    Probability = 5/6

    Step-by-step explanation:

    • Between 22 and 29, 28 can only come once.
    • There are a total of 6 numbers between 22 and 29 (23, 24, 25, 26, 27, 28).

    Step 1: Write the formula of probability

    Probability = number of possible outcomes/total number of outcomes

    There is only one 28 so the chance of getting a 28 is 1/6.

    Not getting a 28 would mean getting any one number from 23, 24, 25, 26 and 27.

    Step 2: Apply the probability formula

    Probability = number of possible outcomes/total number of outcomes

    Probability of not getting 28 = 5/6
