A) Let X be a random variable that can assume only positive integer values, and assume its probability function is P(X -n) A/3^n for some constant A (n> 1). Find A. b) Let X be a continuous random variable that can assume values between 0 and 3, and assume its density function is fx(x)- B(x2 +1) with some constant B (0< x ,3). Find B.

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

180
