Answer:

Step-by-step explanation:
We require more information by I will explain in principle:
If Type A has at least 300 hours and Type B at least 400 hours.

You need to determine the Probability density function of X and Y and then subtract 1 from both

This will give you the probability of the expression.
The solution to this system of linear equations would be (0,2), since you look at the point of intersection. Where the two lines intersect, you look at the corresponding x and y values. Hence, the solution is (0,2). I hope you understand.
