    Answer:

    P = 4 / 6 = 2/3 = 0.66 = 66%

    Step-by-step explanation:

    Assuming the die is numbered 1 to 6.

    To answer the question, we first need to know many prime numbers can be represented on the die.  What are the prime numbers equal to 6 or lower?

    We have 2, 3 and 5.  (since 4 and 6 are not prime numbers).  So we have 3 prime numbers, plus the number 1… so there are 4 possibilities valid for rolling a 1 or a prime number: 1,2,3 and 5.

    4 possibilities out of 6 total possible outcomes, so…

    P = 4 / 6 = 2/3 = 0.66 = 66%

    Answer:

    The probability of rolling a 6 sided die and getting a 1 or a prime number = 2/3

    Step-by-step explanation:

    The numbers on the die are 1, 2, 3, 4, 5 and 6

    To find the probability

    Total outcomes of rolling a die = 6

    Prime numbers less than 6 are 2, 3 and 5

    Possible outcomes(getting 1 or a prime number) =  1, 2, 3 and 5

    Probability of getting 1 or prime number when rolling a die = 4/6 = 2/3
