Probability of independent variables

I want to calculate the probability as
$A=P(W<dfrac{XY^a}{Z^b}).P(W<cY^a)+ P(W>dfrac{XY^a}{Z^b}).P(W<dY^a),$



where, W,X,Y,and Z are independent random variables. X is an exponential random variable, Y and Z are normal random variables, a,b,c, and d are constants. I understand that two terms given above are mutually independent terms. How can I go forward to get "A". Some clues would be really helpful. Perhaps a link to a good book would be great too.
Many thanks

  • A is just a dummy variable that represents the answer of the statement given above
