How many ways can you choose 3 out of 5 books if order doesn't matter

1 answer:

3 0

Since order doesn't matter, we can simply use the combination notation cited as:
$^{n}C_r$ , where n represents the number of objects and r represents the number of subsets.

If we were to choose 3 books from a pack of 5, we can choose them in $^{5}C_3$ ways, which is 10 ways.
