The Catwalk Problem from this lesson is summarized in the diagram below. Given the diagram below, how many outputs does the Catwalk Problem have
for each positive input value?

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

How do you solve a question like this?

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
