Probability of selecting cards and possible area codes
1. A card is randomly selected from a standard deck. Find the probability that the card is between four and eight (inclusive) or is a club.

2. Use the fundamental counting principle:
Until recently, with the advent of cellular phones, modems, and pagers, the area codes in the United States and Canada followed a certain system. The first number could not be 0 or 1, the second could only be 0 or 1, and the third could not be 0. Under this system, how many area codes are possible?
