Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. Five males with an X-linked genetic disorderhave one child each. The random variable x is the number of childrenamong the five who inherit the X-linked genetic disorder. X 012345P(x) 0.0310.1560.3130.3130.1560.031

We can find the second moment given by:

And we can calculate the variance with this formula:

And the deviation is:

Step-by-step explanation:

For this case we have the following probability distribution given:

X          0            1        2         3        4         5

P(X)   0.031   0.156  0.313  0.313  0.156  0.031

The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.

The variance of a random variable X represent the spread of the possible values of the variable. The variance of X is written as Var(X).  

We can verify that:

And

So then we have a probability distribution

We can calculate the expected value with the following formula:

We can find the second moment given by:

And we can calculate the variance with this formula:

And the deviation is:

6 and 24

step-by-step explanation:

6 x 4 = 24

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
