It sounds like you are asking about permutations. In other words, how many ways can you choose 3 items from 4 items in specific orders.The formula is: nPr = n! / (n-r)!In your notation, that would be P(n,r)1. 4P3 = 4! / (4-3)! = 4! / 1! = 4! = 242. 7P1 = 7! / 6! = 7 3. 6! / 4! = 6! / (6 – 2)!n = 6r = 26P2 or P(6,2) in your notation.If the question asks about “combinations” where order does not matter, the formula is nCr = n! / (n-r)! / r!...
