ere are no restrictions. b) Cookie Monster must be in the middle. c) BERT and ERNIE must be together. d) BERT, ERNIE, and OSCAR must be together. e) BERT, ERNIE, and OSCAR must not be together. f) they must not be in alphabetical order.
A) there are no restrictions = 9^9 = 81 b) Cookie Monster must be in the middle = 8^8 = 64 c) <span>BERT and ERNIE must be together = Out of 9, 7 can be rearranged d) </span><span>BERT, ERNIE, and OSCAR must be together = Out of 9, 6 can be rearranged e) UNSURE OF ANSWER E AND F </span>
