this is an example of a discrete random variable, since x can only take on integer values. For a continuous random variable,we cannot use a PDF directly, sincethe probability that xtakes onany exact valueiszero.
while the vertical axis displays cumulative probabilities or percentiles. The curve represents corresponding pairs of x values and cumulative probabilities. For normal CDFs, the function sums from negative infinity up to the value of x, which is (-∞, x] in interval notation.Continuous variablesprod...
