Answer 1

Answer:

52 means 4/52 = 7.69% . If you take a card out of 52 cards if it is not queen you are to leave that set , then take another different card ,another different card so on then there is 7.6% probability to get a queen out of 52 cards . An experiment consists of drawing 1 card from a standard 52-card deck.
