1.<em> </em>Find the probability of rolling less than a four.
<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6
<u>Outcomes lower than four</u> = 1, 2, 3
Then to answer it you need the probability in the form of a fraction.
simplifies into 
2. Find the probability of rolling an even prime number.
<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6
<u>Prime Numbers Through 1-6</u> = 2, 3, 5
<u>Even Prime numbers Through 1-6</u> = 2
So the probability in the form of a fraction.

3. Find the probability of rolling factors of 20.
<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6
<u>Factors of 20 Through 1-6</u> = 1, 2, 4, 5
So probabilty in the form of a fraction.
simplifies into
