Answer

So, the sum of the product of corresponding elements in the two sets X and Y is $\boxed{-5}$.

Steps

Step 1 ：Given the sets of scores X = [1, 2, 3, 5] and Y = [0, 4, -1, -2], we are asked to calculate the sum of the product of corresponding elements in the two sets, denoted as $\Sigma XY$.

Step 2 ：This can be calculated by multiplying each X value with its corresponding Y value and then summing up all the results.

Step 3 ：Doing this, we get: $(1*0) + (2*4) + (3*(-1)) + (5*(-2)) = -5$.

Step 4 ：So, the sum of the product of corresponding elements in the two sets X and Y is $\boxed{-5}$.
