Answer:
Eric,Tony,Jeff,Gary
Step-by-step explanation:
Given the payments made by each individual below:
- Tony paid 35% of the bill.
- Eric paid 3/8 of the bill.
- Jeff paid 0.175 of the bill
- Gary paid 1/10 of the bill.
The most convenient way to order their payments is to convert each to percentage.
Eric paid 3/8 of the bill.
- In Percentage:
Jeff paid 0.175 of the bill
- In percentage, 0.175 X100 =17.5%
Gary paid 1/10 of the bill.
In Percentage:
Therefore, the order from most to least is:
Eric(37.5%), Tony(35%),Jeff(17.5%),Gary(10%)

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.
<h3>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.
