Answer2 Points Keypad Tables First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.
Decide Yes No
Reason Since the probabilities lie inclusively between 0 0 and 1 1 and the sum of the probabilities is equal to 1 1 . Since at least one of the probability values is greater than 1 1 or less than 0 0 . Since the sum of the probabilities is not equal to 1 1 . Since the sum of the probabilities is equal to 1 1 . Since the probabilities lie inclusively between 0 0 and 1 1 .

Five males with an X-linked genetic disorder have one child
each. The 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.

91. Let X be a RV with support set {0, 1, 2}, p(1) =
0.3, and p(2) = 0.5. Calculate E[X]. Let X be a discrete RV. Define
the expected value E[X] of X. Is E[X] constant or random?
Why?
92. Suppose X is a RV with support {−1,0,1} where p(−1)
= q and p(1) = p. What relationship must hold between p and q to
ensure that E[X] = 0?
93. Let X be a discrete RV and a,...

Example Question with answer, My problem is at the bottom.
Fill in the P(X = x) values in the table
below to give a legitimate probability distribution for the
discrete random variable X, whose possible values are −6,
2, 3, 5, and 6.
Value x of X: -6, 2, 3, 5, 6
P(X=x): 0.25, 0.21, 0.13, __, __
EXPLANATION
The values that the discrete random variable X
may take are −6, 2, 3, 5, and 6. Thus, it must be...
