Psychology of the player

Shpilevoy, thank you for the flowers)
I'll start answering click, his problem was earlier.

click writes: I can't calculate the probabilities correctly.

There is a deck of cards 30 pieces. Inside it there are 4 pairs of identical cards (hereinafter referred to as pairs), the remaining 22 are unique.
At the beginning of the game, 4 cards are dealt to each hand.
1) What is the probability that any pair (out of four pairs) of identical cards will come into the starting hand?
2) What is the probability that all 4 cards dealt will be any two pairs?
3) Out of 10 starting hands, what is the probability that a player will receive a pair 3 times?

I have some thoughts about roulette, but the essence of the problem is clearer with cards.

Dear click.
Please unfold this deck in more detail. I need to see it.
It's better to imagine not playing cards, but cards with letters.
ABCDEFG-... 26 letters and also ABCD.
We get a total of 30 cards in the deck, of which 4 pairs are identical.
