    P (multiple of 3) = 2/8 = 1/4 true

    P (odd number) = 4/8 = 1/2 true

    P (factor of 24) = 6/8 = 3/4 true

    P (the number 9) = 0/8 = 0 true

    Step-by-step explanation:

    * Lets explain how to solve the problem

    - There is an 8-sided solid with faces numbered 1 through 8

    ∴ We have the numbers from 1 to 8 (1, 2, 3, 4, 5, 6, 7, 8)

    - Probability is the chance of an event occurring.

    - Ex: the probability of flipping a coin and it being heads is 1/2

    because there is 1 way of getting a head and the total number of

    possible outcomes is 2 (a head or tail)

    - We write P (heads) = 1/2

    * Lets check the answers to find the true statement

    # P (even number)

    ∵ There are 4 even numbers (2, 4, 6, 8)

    ∵ There are 8 numbers

    ∴ P (even number) = 4/8 = 1/2 ≠ 1/8

    # P (multiple of 3)

    ∵ There are 2 multiple of 3 (3, 6)

    ∵ There are 8 numbers

    ∴ P (multiple of 3) = 2/8 = 1/4 true

    # P (odd number)

    ∵ There are 4 odd numbers (1, 3, 5, 7)

    ∵ There are 8 numbers

    ∴ P (odd number) = 4/8 = 1/2 true

    # P (number less than 8)

    ∵ There are 7 numbers less than 8 (1, 2, 3, 4, 5, 6, 7)

    ∵ There are 8 numbers

    ∴ P (number less than 8) = 7/8 ≠ 1

    # P (factor of 24)

    ∵ There are 4 factors of 24 (1, 2, 3, 4, 6, 8)

    ∵ There are 8 numbers

    ∴ P (factor of 24) = 6/8 = 3/4 true

    # P (the number 9)

    ∵ There is no 9

    ∵ There are 8 numbers

    ∴ P (the number 9) = 0/8 = 0 true
