Generate two random numbers between 0 and 1 and take X to be their sum. The sum Y can take
any value between 0 and 2. The density curve of X is the triangle shown in Figure 10.7 (below).
9.Which one of the following statements verifies by geometry that the area under this curve is 1?
A.The area of a triangle is found from the formula Generate two random numbers between 0 and
1 and take X to be their sum. The sum Y can take any value between 0 and 2. The density curve
of X is the triangle shown in Figure 10.7 (below).
Solution
9) A. The area of a triangle is found from the formula.
