OK. What are the known facts? We need 20 servings, and 1/3 cup is for 8. Let's move things around. Think as if 1/3 was for 5 people. That would mean you would need 1 1/3 cups for 20 servings. Because 5*4 is 20 and 1/3*4 is 1 1/3. Now for the extra 3. There are 4 sets of 3 total left, which is 12. 12 is 1 1/2 of 8, so we need 1/3 cup and half of 1/3. I don't want to give the entire thing away, so I will leave that for you to figure out! Bye :D

Answer:
0.45
Step-by-step explanation:
1. 3.15÷7=0.45
2. 3.20÷8=0.40
3. 4.10÷10=0.41
4. 4.18÷16=0.26
We need to find the probability of atleast one failure in 5 trails
Probability of success = 30% = 3/10
The opposite meaning of atleast one failure is all success (no failures)
Probability of (atleast one failure ) = 1- Probability ( success)
First we find probability of success
Formula for binomial distribution
All success so n=5, r=5, p= 3/10, q= 1-p = 7/10
Probability (success) =
=
Probability (atleat one failure) = 1 -
= 0.92224
= 92.2%
