Problem 2 This is a basic problem on Combinations and Permut
Problem #2: This is a basic problem on Combinations and Permutations.
Here are 7 letters: A, L, T, E, M, P, N. How many COMBINATIONS can you make from these letters (they don’t have to spell actual words)?
How many PERMUTATIONS can you make?
What is the longest actual word you can make from these letters?
Would Combinations or Permutations typically be a larger number?
Can you give an example with letters or numbers where both would be the same? (Not a yes/no question)
Solution
there are total 7 letter
combinations can be made from 2 lettes like 7C2 = 21
7C3 = 35
7C4 = 35
7C5 = 21
7C6 = 7
7C7 = 1
B)PERMUTAIONS WILL BE 7! AS WE HAVE 7 LETTERS AND CAN BE ARRANGED IN 7! WAYS
C) LONGEST WORD WILL BE 6 LETTER WORD LIKE MANTLE
D)NO THIS IS NOT POSSIBLE
