Wow, just started this class and it is way over my head... :eek:

1. Twelve points are placed on the circumference of a circle and all the chords connecting these points are drawn. What is the largest number of points of intersection for these cords?

2. In how many ways can the letters in WONDERING be arranged with exactly two consecutive vowels?

What does the exclamation point mean next to a number 5!?
