How many 6 digit even numbers can be formed from digits?
= 720 ways. Therefore, 720, six digit even numbers can be formed.
How many 5 digit even numbers can be formed using the digits 1 2 3 4 5 if digits are not allowed to repeat?
1080. You can make 1080 5-digit even numbers from 1,2,3,4,5,6,7 if no digit is repeated.
How many variations of 6 digit numbers are there?
If you are just using the digits from 1 to 6, the answer would be 6*5*4*3*2*1 = 720, because you have 6 choices for the units digit, and then 5 choices left for the tens, and then 4 choices left for the hundreds and so on.
How many four digit numbers can be there with no repeated?
At ten’s place = There are now 8 digits to be filled as 2 digits are already taken = 8 ways Total Number of ways to fill the four places = 9 × 9 × 8 × 7 = 4536 ways. So a total of 4536 four digit numbers can be there with no digits repeated.
How many numbers can be formed with 5 digits?
We’ve to form numbers containing 5 digits. So r=5. =5!/ (5-5)! =5!/0! =120 ways. Final answer: from the given digits 1,2,3,4,5 we can for 120 numbers which contain 5 digits. How many numbers of five digits can be formed with the digits 1,2,3,4 and 5: with repetition?
How do you find the second last digit in even numbers?
To form even numbers, the units digit should be either 2,4 or 6. Therefore, there are three ways. Now, since the second last digit is also even. Since, from the three numbers, one of the numbers is used in the units place. Therefore, there are 2 ways for the second last digit, as the digits should not repeat.
How many possibilities does each digit in the number 6 have?
Two answers are possible. One is with the repetition of digits. The other is without repetition of digits. 1st digit can be filled by any of the 6 numbers. Similarly 2nd, 3rd and 4th digits. Hence each digit will have 6 possibilities. Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
