Step-by-step explanation:
<span>Given are the following data:
Heart failure causes:
84% natural occurence
16% outside factors
18 individuals (sample size)
1. What is the probability that 3 individuals have conditions caused by outside factors?
Probability = 3/18 * 0.16 = 0.0267 or 2.67%

This is not a random sample since she is outside of a pet store and the probability of people owning a dog coming out of that store is very very high. If she went around the neighborhood and knocked on people’s door and asked if they had a dog or not would be random sample.
1 and one - twelfth
because 12gies 3 times in 37
18 / 1 = x / 15......18 miles to 1 gallon = x miles to 15 gallon
cross multiply
(1)(x) = (18)(15)
x = 270 miles
