to visualize the example of card dropping in a bar graph, it would be something like this: This is a discrete version of the probability density function. Let’s say the width of each bar is always 1. Then the area for Pr(x=0) is 0.4 * 1 = 0.4. Same goes for the Pr(x=1). Note that the sum of all the
