Different Permutations:The factorial of a number is the product of all the consecutive numbers from the given number to {eq}1 {/eq} in decreasing order. The number of different permutations using the elements of a set with {eq}n {/eq} elements is {eq}n! {/eq}....

5. How many permutations of the numbers { 1, 2, 3, 4, 5, 6 }:(a) begin with an even number?We must start off with one of the 3 even numbers:口Now we have 5 items left and can continue using our basic permutation:354321We now have 3 × 5 × 4 × 3 × 2 × 1 =...
The hundreds, tens, and units place is to be filled by the remaining9 digits.Therefore, there will be as many such 3-digit numbers as there are permutations of 9different digits taken 3 at a time.Number of such 3-digit numbers = = = =9 8 7=504Thus, by multiplication principle, the...
Example problem: If there are 5 people, Barb, Sue, Jan, Jim, and Rob, and three will be chosen for the new Parent Teacher Association. The first person picked will be the president, then the vice president, then the secretary. How many permutations are possible for the committee? ...
each comparison,the adversary considers how many permutations of the keys are consistent with both possible answers.It gives the response consistent with the most permutations.Thus after each comparison,the number of remaining permutations is at least half as many as before the comparison.There are ...
There is exactly one class of similarity for nilpotent matrices of order nn. The question I would like to ask: How many nilpotent matrices of order kk are there up to similarity? The answer is 11 if k=nk=n. The answer is 11 again if k=1k=1. (The null matrix is...
