Mathematics 2002 JAMB Past Questions - Question 47: How many three -digit number can be formed from 32564 without any digit being repeated?

Correct Answer

D

Explanation

To find the number of three-digit numbers that can be formed from the digits 3, 2, 5, 6, and 4 without any digit being repeated, we can use the concept of permutations.Since we have 5 digits to choose from, we have 5 choices for the first digit, 4 choices for the second digit (as one digit has already been used), and 3 choices for the third digit (as two digits have already been used).Therefore, the total number of three-digit numbers that can be formed is:5 * 4 * 3 = 60So, there are 60 three-digit numbers that can be formed from the digits 3, 2, 5, 6, and 4 without any digit being repeated.
