Answer:

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

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.

(X>3)(Y>4)=P(X>3)P(X>4)

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

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

This will give you the probability of the expression.

Multiply 105 and 100= 10,500

then divide by 70 = 150
