Question

You roll a 6-sided die.

What is P(prime or factor of 49)?

Answer 1

When a die is rolled. The sample space(S) of this die is equal to 36 so the prime factor of 49 is 1, 7 and 49 the probability (p)= 3/36

So answer is 0.08333...

Answer 2

prime numbers include 2, 3, and 5

Pr(prime) = 1/2 = 50%

none of the numbers 1 through 6 are integer factors of 49,

except for 1

factors of 49 are 1, 7 and 49

Pr(prime or 1) is 4/6 = 2/3 = about 67%
