If you are asked to list in order of preference, the three best movies you have seen this year and you have seen 10 movies this year. How many different ways can the three best be chosen and ring?



Answer :

Answer:

720 possible ways

Step-by-step explanation:

To list the three best movies out of 10 you've seen this year and considering their order of preference, you would use a combination. The formula for choosing kk items out of nn items, where order matters, is given by:nPk=n!(n−k)!nPk=(n−k)!n!​Where nn is the total number of movies you've seen this year and kk is the number of movies you want to select as your top three.In this case:n=10n=10 (total number of movies seen)

k=3k=3 (selecting the top three)Plugging the values into the formula:10P3=10!(10−3)!10P3=(10−3)!10!​10P3=10!7!10P3=7!10!​10P3=10×9×8×7!7!10P3=7!10×9×8×7!​10P3=10×9×810P3=10×9×810P3=72010P3=720
