Answer:

125 digits

Step-by-step explanation:

Since we have to find the number of 3 digit numbers with odd digits (Do not have an even digit or Zero).

Since Zero is an even digit so we have the options of only 1,3,5,7,9 to be filled at these 3 blanks.

For 1st blank number of ways to fill with replacement allowed is 5 (1,3,5,7,9)

For 2nd blank number of ways to fill with replacement allowed is 5 (1,3,5,7,9)

For 3rd blank number of ways to fill with replacement allowed is 5 (1,3,5,7,9)

So,Total numbers of 3 digits in given situation are

5*5*5=125
