Explanation:

A hypergeometric distribution as a function of statistical distribution where members from two groups are analysed,  without replacing those members. Unlike binomial distributions, in which the probability remains the same for each trial, in hypergeometric distributions, these members are not replaced- each trial's probability affects the probability within next trial.

This is used in the process of random sampling and as a means of quality control in statistics; for example selecting members of a sports team from a mixed population of boys and girls.

Hypergeometric Formula..,

For a population consisting of N items, k are successes. And a random sample from that population consisting of n items, x of which are successes.

∴ hypergeometric probability is:

h(x; N, n, k) = [ kCx ] [ N-kCn-x ] / [ NCn ]

this distribution always has... 

  • its mean=  n * k / N .
  • its variance  is n * k * ( N - k ) * ( N - n ) /  [ N2 * ( N - 1 ) ] .

Thus….

Total number of bottles =  22

Number of contaminated bottles = 6

Number of tested bottles = 4

X= a random variable representing the number of contaminated bottles selected for the test.

N = 22

K = 6

n = 4

The probability mass function, f(x), is given by...

P(X=x)) = [ kCx] [ N-kCn-x ] / [ NCn ]    x= 0,1,2,3,...,n

           = \frac{[6 C 1] [22-6 C 4-1]}{[22 C 4]}

OR          

\frac{C\left \ {{k=6} \atop {x=1}} \right.   C\left \ {{22-6} \atop {4-1}} \right. }{C \left \ {22} \atop {4}} \right. }

Cxk= C14= 4!(1!(4 - 1)!)^{-1}= 24(6)^{-1}= 4\\Cn-xN-k=C\left \ {{22-6} \atop {4-1}} \right. } =16!(4!(16-4)!)^{-1}\\(CnN)^{-1}=(C \left \ {{y=22} \atop {x=6}} \right. ) ^{-1}=[22!(6!(22-6)!)^{-1}]^{-1}

f(x)= p= P(X=1)=0.45933014354067

P(that more than 1 of the tested bottles is contaminated);

P(X>1)=1−P(X≤1)=1−(P(X=0)+P(X=2))

                P(X>1)=0.291866028708134

Probability that one is contaminated: 0.4593(4 dec places)

Probability that more than one is contaminated: 0.2919 (4 dec places)

Keith_Richards [23]

Answer:

The correct answer is b. Alcohol consumption and smoking can affect men's sperm and are associated with known birth defects.

Explanation:

According to different observational studies, it has been concluded that approximately the concentration of sperm in optimal conditions, taking into account its morphology and movements, is reduced by 13% for smokers compared to non-smokers. In addition to 25 other studies of the same type that have been carried out, which lead to the conclusion that the consumption of substances such as alcohol and tobacco, are harmful to male fertility and can also lead to the development of some inherited disorders such as cancer Autism spectrum disorder, among others.
