I need a problem made up, as well as a solution.
Permutations and combinations (Should include at least two examples)Solution
Permutations: An arrangement where order is important called permutations.
Combinations: An arrangement where order is not important known as combinations.
Problem on permutations:
Suppose 12 people needs to go to paris, but we have only 5 tickets, then in how many ways can we choose 12 people for 5 tickets.
Ans:
12C1 *11C1*10C1*9C1*8C1* = 12*11*10*9*8 = 95040 ways
Problem on combinations:
Question: you have to choose three movies from 5 different movies, in how many can you choose the movies:
Ans:
5C3 = 5!/(3!*2!) = 10 ways
