Change [math]n[/math] to alter the number of bars.[br][br]The height of each bar is probability density so the area of each bar gives the probability.[br][br]To work out [math]p(0\le x \le m)[/math] add up the areas of the bars. You can see this by changing [math]m[/math].[br][br]What would be a better way to work out [math]p(0\le x \le m)[/math] especially when [math]n[/math] is large?
