The area of a square, in square feet, depends on the length of its sides, in feet. This is written in function notation as a(s). What is the best interpretation of a(4) = 16?

Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

Write as a product: ac^2–ad+c^3–cd–bc^2+bd
