Answer:
Step-by-step explanation:
If you start with a 52 card deck which includes 4 sevens and remove a seven and another card, then the (number of sevens in the deck) is 3 and the (number of cards) is 50. So, in that specific case, assuming that the cards are arranged in a uniform random order, the answer would be 3/50.
You have four cards in the deck with the number 7.
Your probability is 1/13.
