    not sure, they have to tell you what exactly this density graph is like, if its a perfect normal distribution and what the Standard deviation is

    now u see the base is length 0 to 80

    and the height has to be such that the area of the triangle is 1, everythjing has to add upto 1

    so what does the height of the triangle have to be so the area is 1?

    and it can be any triangle, the height will always be the same, because the area has to be 1, and the base is fixed at 80
