A local paint store carries 4 brands of paint (W, X, Y, and Z).
The store has 15 cans of W, 10 cans of X, 9 cans of Y, and 16 cans
of Z, all in white. It is thought that customers have no preference
for one of these brands over another. If this is the case, what is
the probability that the next 20 customers will select 4 cans of W,
3 cans of X, 4 cans of Y...

Let w = (x 2 -z)/ y4 ,
x = t3+7,
y = cos(2t),
z = 4t.
Use the Chain Rule to express dw/ dt in terms of t. Then
evaluate dw/ dt at t = π/ 2
