WebbIf \(X\) is a random variable of a random draw from these values, what is the probability you select 2? If we assume the probabilities of each of the values is equal, then the probability would be \(P(X=2)=\frac{1}{5}\). We can define the probabilities of each of the outcomes using the probability mass function (PMF) described in the last section.
