Question

Students are chosen in groups of 6 to tour a local business. How many ways can 6 students be selected from 3 classes totaling 53 students?

Answer 1

`22.16xx10^9`

Explanation:

The way to find how many possibilities there are is by taking the number of items - `53` - and putting it to the power of how many are chosen - `6` -.

For example a `3` digit code which could have the numbers `0 to 9` would have `10^3` possibilities.

`53^6=22.16...xx10^9`
