Answer:
Or
Step-by-step explanation:
We can represent this situation with an equation that shows that when b and p are added, then the total number of people will be 72
The number of people who bring supplies = b
The number of people, to whom supplies are provided = p
We get ;
Or
Answer:
79.17% probability that brandy will roll a strike the first frame of the next game
Step-by-step explanation:
The experimental probability is the probability based on previous outcomes, that is, the number of desired outcomes divided by the number of total outcomes.
While bowling with friends, Brandy rolls a strike in 57 out of 72 frames. What is the experimental probability that brandy will roll a strike the first frame of the next game?
Desired outcomes:
57 strikes
Total outcomes:
72 frames
Probability:
p = 57/72 = 0.7917
79.17% probability that brandy will roll a strike the first frame of the next game
14n + 21
Just distribute the 7 to the 2n and the 3.
7(2n + 3)
(7 * 2n) + (7 * 3)
14n + 21

This is a case of binomial probability, with n = 29, p = 0.11 and x = 5.
Using the function binompdf on my Texas Instruments calculator, as follows:
binompdf(29,0.11,5) = 0.117 (answer)
The smallest decimal is 0.019
