Five males with an X-linked genetic disorder have one
random variable x is the number of children among the five who inherit
the X-linked genetic disorder. 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.

A survey showed that 35% of human resource professionals are at companies that rejected job candidates because of information found on their social media. If 25 human resource professionals
are randomly selected, would 14 be a significantly high number to be at companies that rejected job candidates because of information found on their social media? Why or why not?
Select the correct choice below and fill in the answer box within your choice.
(Round to four decimal places as needed.)
A. No, 14 would not be significantly high because the probability of 14 or more is
B. Yes, 14 would be significantly high because the probability of 14 or more is
C. Yes, 14 would be significantly high because the probability of 14 or more is
O D. No, 14 would not be significantly high because the probability of 14 or more is
which is not low.
