Answer:
1)
3)
5)
Explanation:
1. Find the probability of rolling less than a four.
Probability Outcomes = 1, 2, 3, 4, 5, 6
Outcomes lower than four = 1, 2, 3
Then to answer it you need the probability in the form of a fraction.

2. Find the probability of rolling an even prime number.
Probability Outcomes = 1, 2, 3, 4, 5, 6
Prime Numbers Through 1-6 = 2, 3, 5
Even Prime numbers Through 1-6 = 2
So the probability in the form of a fraction.
3. Find the probability of rolling factors of 20.
Probability Outcomes = 1, 2, 3, 4, 5, 6
Factors of 20 Through 1-6 = 1, 2, 4, 5
So probabilty in the form of a fraction.
