Find the probability of rolling a prime number on a dice
1 answer:
A dice has numbers 1 through 6. Prime numbers are numbers that cannot be divided by anything except itself and one. Remember that 1 is not a prime number.
That means the numbers on a dice that are prime are: 2, 3, and 5. That means 3 out of the 6 numbers are prime, so the probability of rolling a prime number, since all sides have the same chance of being rolled is:
Your answer is 1/2 probability of rolling a prime.

Using the place value chart we can see that the decimal 0.6 is six tenths, so we can write 0.6 as the fraction . Notice however that
is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 10 which is 2.
