Discrete and continous probability density functions

When a fair coin is tossed times, the probability bar graph can be displayed in the interactive figure, where can be varied with the slider. The probability of getting between and (inclusively) successes is

When working with a continuous random variable that is a probability density function , the probability of getting between and successes is

This can also be demonstrated in the interactive figure. When the continuous normal distribution model is shown, you can vary and by moving the points on the -axis.
