A new clothing store has a unique method of pricing items. A vest costs $20, a tie costs $15, a blouse costs $30, and underwear costs $45. How much would pants cost?
I have two coins.
* One of the coins is a faulty coin having a tail on both sides of it.

What is the probability that another side is also tail?
