Question


Roger drew one card from a standard deck of 52 cards. What is the probability that the card Roger drew is not a seven?

1 Answer

  • Answer: 12/13

    Step-by-step explanation:

    In a deck of cards there are 4 of each number. Therefore there are 4 sevens in the deck. 4/52 are 7, but you want the probability of getting a card that IS NOT 7. That means there are 48 cards that aren’t a 7. 48/52 is the probability. But you can simplify this by finding a number that divides evenly into both, which in this case is 4. This simplifies to 12/13.
