What is RVS function?

• A RV X is a function that assigns a real valued number x = X(ξ) to each outcome ξ ∈ S (Recall: a function is a rule for assigning a numerical value to each element of a set). • Sample space S is the domain of the RV X and the set of all real numbers taken on by X, Sx, Sx ⊂ R, is the range of the RV.

What is the shape of the most probability distribution?

The single most important distribution in probability and statistics is the normal probability distribution. The density function of a normal probability distribution is bell shaped and symmetric about the mean. The normal probability distribution was introduced by the French mathematician Abraham de Moivre in 1733.

Is PX Y a random variable or a number?

I reason that is a random variable because Y is a random variable, thus making Px acting randomly. Example Y sample space is a roll of a die (1,2,3,4,5,6). So any of those values could be inputed in pX, thus making it act as a random variable.
