Hello, this problem is a little tricky for me. Can you help me?

I have a 11 cards deck composed of ten cards from 0 to 9 and one Joker. (that can represent any number from 0 to 9)

I pick two cards to make a two digit number, the first one will represent the tenths and the second one is the units. The Joker will be the same number as the other card that is picked, so if i draw a 6 and a Joker i get 66.

I am not sure of how many combinations do i have here. Do i have 100 or 110 combinations?. All the combinations of the Joker beign Card N1 appear in the other combinations with cards from 0 to 9.

The probability of picking the Joker is 1 /11 but the joker will not have a value until we pick the second card, so after picking the Joker it has 1/10 probability of being any number from 0 to 9.

Can i say that picking the Joker as first card doenst make any difference in the probabilities ? Picking the Joker first or second does change the probabilities?

The problem is that i just want to have 100 different results (0 to 99) and not 110.

I made a table with all the possibilities, the first column is Card N1, second column is Card N 2, third column is Result.
