Answer:
Step-by-step explanation:
5/6 = 14*5/14*65/6 = 5/6
This is binomial probability with n=50 and p=0.62.
We want binom(50,0.62,35).
One way to calculate this is to use a calculator with statistical functions.
My TI-83 Plus turned out the result 0.061.
3.528571429
Hope This Helps!!
In order to find out what deal is better:
- We have to find the unit rate for each deal
- Total amount of paper towels ÷ The price
So it would be....
- 18 ÷ 14 = 1.285714
- 12 ÷ 10 = 1.2
Short Answer:
The better deal is 10 rolls of paper towels for $12.
Long Answer:
I wanted to find out the price per roll of paper towel for each deal so I created a unit rate problem which is the numerator divided by the denominator. From there, I was able to get my answers, compare which one was less than the other, and select the best deal.
Hopefully this helped >-<
