The answer depends on how many digits are used to display the time: 4 (hh:mm) or 6 (hh:mm:ss)?
There are more 12-digit palindromic numbers than 11-digit palindromic numbers. This is because the number of possible 12-digit palindromic numbers is greater than the number of possible 11-digit palindromic numbers. In general, the number of palindromic numbers of length n is 9 * 10^((n-1)/2), so for 11-digit palindromic numbers, there are 9 * 10^5 = 900,000 possibilities, while for 12-digit palindromic numbers, there are 9 * 10^6 = 9,000,000 possibilities.

Assuming you mean digits and not didgets, the answer is 6.

There are 60480 numbers.
6*5*4*3*2*1=720 possible numbers
6*6*3 = 108 numbers.
Assuming you mean digits and not didgets, the answer is 6.
There are 6 odd digits.There are 6 odd digits.There are 6 odd digits.There are 6 odd digits.

120 There are 6 digits in total. The numbers with 3 digits, with all digits distinct from each other, are the permutations of the 6 digits taken 3 at a time, and therefore there are 6*5*4 = 120 of them.
