Answer 1

with repetion of digits ,total no. = 1875

Answer 2

Answer:

Total combination of numbers are 1875

Step-by-step explanation:

Given : The number of 5 digit odd numbers that can be made from number 12345

To find : How many numbers can be form

Solution : We know to make a number odd we just need that last digit should be an odd number.

odd numbers in 12345 = 1,3,5

Therefore last digit is fixed with 3 possibilities of odd number 1,3,5

Let take a number A B C D E

As it is not mention that number doesn't repeat so we apply repetition.

So possible numbers for E = 3 -  (1,3,5)

Possible numbers for D = 5 -  (1,2,3,4,5)

Possible numbers for C = 5 -  (1,2,3,4,5)

Possible numbers for B = 5  - (1,2,3,4,5)

Possible numbers for A = 5  - (1,2,3,4,5)

Therefore, Total combination of numbers are = 5 ×5×5×5×3 = 1875
