Question: If the joint density function for X and Y is given by find the value of the constant C. Then find P(X 7, Y

If the joint density function for X and Y is given by 

f(x, y) = [C(x + 2y) if 0x 10, 0 y 10 otherwise

find the value of the constant C. Then find P(X ≤ 7, Y ≥ 2).

f(x, y) = [C(x + 2y) if 0x 10, 0 y 10 otherwise
