Question

The number of ways in which $6$ rings can be worn on the four fingers of one hand is?

• A. $4^6$
• B. ${}^{6}C_4$
• C. $6^4$
• D. None of these

Answer 1

The correct option is A

$4^6$

Explanation for the correct option:

Find the required number of permutations.

We have to arrange $6$ rings on $4$ fingers

Since all the $6$ rings have $4$ choices for fingers.

So, the total number of ways is $4·4·4·4·4·4=4^6$.

Therefore, The number of ways in which $6$ rings can be worn on the four fingers of one hand is $4^6$.

Hence, option $A$ is the correct answer.
