The CDF of the random variable X is defined by 0
x <2
FX(X) = A(x - 2)2<r<6

r > 6
(a) What is the value of A?
(b) With the above value of A, what is P[X > 41?
(c) With the above value of A, what is P[3 < X <5]?​

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
