Answer:
0.3165
Step-by-step explanation:
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of adults sampled = 9
x = Number of successes required = number of selected adults that say they were too young to get tattoos = 0
p = probability of success = probability of an adult that regrets getting a tattoo saying they were too young to get the tattoo = 12% = 0.12
q = probability of failure = 1 - p = 1 - 0.12 = 0.88
P(X=0) = ⁹C₀ (0.12)⁰ (0.88)⁹⁻⁰
P(X=0) = 0.31647838183 = 0.3165

56 miles
If Lou ran 72 more miles than lee. Just subtract 72 from 128 (128-72) and you get 56.
2/35, just ask your calculator what is one seventh of two and one half.<span />
D = | -12 - 9 | = -21
d = | -2 - (-7) | = 5
d = | 25 - (-1) | = 26
