Combinatorics and Permutations: A Comprehensive Exercise on Counting and Arrangement Principles Chapter8 Quiz 1.Evaluate the expression. 100 P 1 = 100! / (100 - 1) = 100 ! / 99! =100 x 99!/99! =100 answer 2How many permutations are there of the following word? COMBINATORICS solution: here there are 13 letters. but in this word there are 2 C's,2 O's ,2 I's. so permutations will be: 13! / 2! X 2! x 2! =13!/8 = answer 778377600 3.Evaluate the expression.(They dint show this as fraction on homework,just 4 over 9) (4/9) 4.Decide whether you would use a permutation, a combination, or neither. Next, write the solution using permutation notation or combination notation, if possible, and,
