Question

In how many ways 6 rings of different types can be worn in 4 fingers?

Answer 1

The first ring can be worn in any of the 4 fingers. So, there are 4 ways of wearing it.

Similarly, each of the other rings can be worn in 4 ways.

So, the required number of ways = (4 × 4 × 4 × 4 × 4 × 4) = 4⁶.
