Given that x is a hypergeometric random variable with Nequals10​, nequals4​, and requals6​, complete parts a through d. a. Compu
sergey [27]

Answer:

a. 0.114

b. 0.005

c. 0.381

d. 0.00

Step-by-step explanation:

If x follows a hypergeometric distribution, the probability that x is equal to k is calculated as:

P(x=k)=\frac{(rCk)*((N-r)C(n-k))}{NCn}

Where k≤r and n-k≤N-r, Additionally:

aCb=\frac{a!}{b!(a-b)!}

So, replacing N by 10, n by 4 and r by 6, we get:

P(x=k)=\frac{6Ck*((10-6)C(4-k))}{10C4}=\frac{6Ck*(4C(4-k))}{10C4}

Then, the probability that x is equal to 1, P(x=1) is:

P(x=1)=\frac{6C1*4C3}{10C4}=0.114

The probability that x is equal to 0, P(x=0) is:

P(x=0)=\frac{6C0*4C4}{10C4}=0.005

The probability that x is equal to 3, P(x=3) is:

P(x=3)=\frac{6C3*4C1}{10C4}=0.381

Finally, in this case, x can take values from 0 to 4, so the probability that x is greater or equals to 5 is zero.
