Dear Stacey Koprince,
Many thanks for your ongoing help. I have two questions if you don't mind:
1)What's the difference between a and b below:
a. In how many different orders can the people Alice, Benjamin, Charlene, David, Elaine, Frederik, Gale, and Harold be standing on line if each of Alice, Benajmin, Charlene, must be on the line before each of Frederic, Gale and Harold?
b. In how many different ways can the letters A,A, B,B,B,C,D,E be arranged if the letter C must be to the right of letter D?
I did not really understand why we didnt use the 8! in the formula in a, but rather, we multiplied 28x2x6x6=2016 ways
2)In arcs and circles, when do I use the tip that the measure of an arc is twice the measure of its corresponding interior angle?
Thank you!
