How many 3 digit numbers can be formed from the digits 1 2 3 4 and 5 how many different 3 digit odd numbers can be formed?

Permutations and Combinations = m x n x p = 5 x 4 x 3 = 60. How many 3-digit numbers can be formed from the digits 1, 2, 3, 4 and 5 assuming that repetition of the digits is allowed. Number of places for the digits = 3. ∴ By fundamental principle of counting, the number of 3-digit numbers formed.

How many three digit numbers that are odd can be formed whose digits are distinct?

Thus there are 60, 3 digit numbers, with distinct digits, with each of the digits odd.

How many different natural numbers can be formed using the digits?

Final Conclusion: The number of 3-digit even numbers that can be formed using given digits, with repetition allowed, is 168. The number of 3-digit even numbers that can be formed using given digits, without repetition of digits, is 45.

How many natural numbers can be formed?

Now, for 1 digit natural number, at 1st place we have 5 digits and we can’t include 0 because zero is not a natural number. Hence, the total number of natural numbers is 215.

How many natural numbers not exceeding 4321 can be formed with the digits 1 2 3 4 if the digits can be repeated?

As there are 4 digits 1, 2, 3, 4 and repetition of digits is allowed. ∴ Total number of natural numbers not exceeding 4321 = 4 + 16 + 64 + 229 = 313.

How many 3 digit numbers can be formed from the digits 123456789?

Assuming leading zeros are not allowed, the first digit of a 3-digit decimal number must be one of the nine digits [123456789]. For each of these nine leading digits, there are 100 possibilities for the next two digits: from 00 thru 99, so there are 900 possible three-digit numbers.

How many even 3-digit numbers are there?

There are a total of 900 3-digit numbers. Of these half of them are even number and the remaining half are odd numbers. Hence there are 900/2 = 450 even 3- digit numbers. Can a 3-Digit Number have Two Zero’s?

Can the hundreds digit of a three digit number be zero?

But, if we DON’T first choose zero for the units digit, then the hundreds digit cannot be zero, since the resulting number wouldn’t be a 3-digit number (e.g., 046) is not a 3-digit number). Also, the hundreds digit cannot be the same as the units digit (since all 3 digits are DIFFERENT).

What is the sum of three natural numbers A B C?

Sum of three Natural numbers a, b and c is 10. How many ordered triplets (a, b, c) exist? Sum of three Whole numbers a, b and c is 10. How many ordered triplets (a, b, c) exist? In how many ways 11 identical toys be placed in 3 distinct boxes such that no box is empty? a, b, c are three distinct integers from 2 to 10 (both inclusive).

What is the smallest 3-digit number that can start with 0?

100 is the smallest 3-digit number and 999 is the greatest 3 digit number. A 3-digit number cannot start with 0. 10 tens make 1 hundred which is the smallest 3 digit number and 10 hundred make a thousand which is the smallest 4 digit…
