Question

If a number cube is rolled once, which is the more likely outcome, a prime number or a composite number?

Answer 1

Remember that

we have 3 prime numbers (2,3,5)

and

we have two composite numbers on a 6 sided die (4,6)

therefore

The probability of getting a prime number is P=3/6=1/2=0.5

The probability of getting a composite number is P=2/6=1/3=0.33

therefore

The more likely outcome is a prime number
