Probability & Statistics Ch.2 Section 1 Question 1

Finding minimum and maximum values of random variables X(s)=s² and Y(s)=1/s on the sample space S={1,2,3...}

Determining whether relations between random variables X, Y, and Z are true or false on a finite sample space

Defining nonconstant random variables and computing Z(s) = X + Y² for all elements in a sample space

Computing Z(s) = XY for rolling a fair six-sided die where X(s)=s and Y(s)=s³+2

Exploring whether random variables must be non-negative and when X + c ≥ 0 holds

Can an unbounded random variable be defined on a finite sample space?

Is Y = √X a random variable if X is a random variable?
