    Prime number between 1 and 8 = 2,3,5,7
    So 4/8 = 50% of the number

    So 0.5 x 100 = 50 times

    Answer:

    the numbers on an 8-sided die are 1, 2, 3, 4, 5, 6, 7, and 8

    2, 3, 5, and 7 are prime numbers

    half the numbers are prime

    you should roll a prime number half of the time (theoretically)

    if you roll the die 100 times, you (theoretically) should get a prime number 50 times, which is half of the time
