Answer:
a) The value of A = 2
b) The value of
Step-by-step explanation:
a)
Given that:
X should be the random variable that assumes only positive integer values.
The probability function; for some constant A and n ≥ 1.
Then, let
This implies that:
A = 2
Thus, the value of A = 2
b)
Suppose X represents a e constant A (n> 1). Find A.
b) Let X be a continuous random variable that can assume values between 0 and 3
Then, the density function of x is:
where; B is constant.
Then, using the property of the probability density function:
Taking the integral, we have:
B [ 9 +3 ] = 1
B [ 12 ] = 1
Divide both sides by 12
