How do I calculate chances?
If there s 100 cards and 10 are my cards, how big is my chance to get the right card twice in a row?
If there s 100 cards and 30 are my cards, how big is my chance to get the right card 3 times in a row?

If there s 100 cards and 30 are my cards, how big is my chance to get the right card 3 times in a row?

i) P = 1/100
ii) P = 27/1000
