In a deck of cards there are 52 cards numbered from 1 to 13. There are 8 cards of each number in the deck. If you insert 12 more cards with the number 10 on them and you shuffle the deck really good, what is the probability to pull out a card with a number 10 on it?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
