Permutatuon question help!! PLEASE 1. How many ways can the word PAIRS be arranged if the first letter cannot be a vowel. 2. I believe you would just use counting, maybe (n!)/(n-r)! 3. 3x4x3x2x2=72. I put 3 as the first number because there are 3 different combinations not using a vowel. I believe this is right, but i dont understand why. Can somebody explain this to me? I came up with the rest of the numbers, knowing that 72 is the answer. But i'm not sure why i would use these combinations of numbers. Thanks Second problem: 1. Using the letters from the word equation, how many five letter patterns can be formed in which q is followed immediately by u? 2. I believe you would just use counting, maybe (n!)/(n-r)! 3. I'm not even sure where to start with this one. I get thrown off by the 5 letter pattern even though there are 8 numbers. i tried many things and cant seem to come up with the right answer which is 580. Thanks so much guys, I have a large test tomorrow and really appreciate the help.
