Answer in Statistics and Probability for bang #243473
Just from $13/Page The objective of the problem is to find the probability that a waitress will refuse to serve alcoholic beverages to only 2 minors. The objective of the problem is to obtain the probability that a waitress will refuse to serve alcoholic beverages to only 2 minors by using 5 students from among 9 students of which 4 are not of legal age. The probability that a waitress will refuse to serve alcoholic beverages to only 2 minors are obtained below: The required probability is, “h(x; N=9,n=5,k=4) = \frac{\binom{k}{x} \binom{N-k}{n-x}}{\binom{N}{n}}” where max{0, n-(N-k)} ≤x≤ min{n,k} i.e. 0 ≤x ≤4 “P(X=2) = \frac{\binom{4}{2} \binom{9-4}{5-2}}{\binom{9}{5}} \\n= \frac{\binom{4}{2} \binom{5}{3}}{\binom{9}{5}} \\n= \frac{\frac{4!}{2!(4-2)!} \times \frac{5!}{3!(5-3)!}}{\frac{9!}{5!(9-5)!}} \\n= \frac{10}{21} = 0.47619” The probability that a waitress will refuse to serve alcoholic beverages to only 2 minors is obtained by substitute the value of n, m, x, and N in the hypergeometric distribution formula. It can be expected that about 47.621% of the times waitresses will refuse to serve alcoholic beverages to only 2 minors. Thus the answer is 0.4762 # What Will You Get?
