From a deck of cards, Jeff took out one card at random. What is the probability that he got a prime number?




Step by Step Explanation:
  1. There are 52 cards in a deck, with 13 cards of each suit (diamond, club, heart, and spade).
  2. 13 cards of a suit are the numbers from 2 to 10, 3 face cards and 1 ace card.
  3. From the numbers 2 to 10, only 2, 3, 5, and 7 are prime. So there are four prime numbered cards per suit, which gives a total of 16 prime numbered cards.
  4. So, there are 16 prime numbered cards out of a total of 52 cards.
    So, the probability that we pick a prime numbered card =  
    Number of prime numbered cards
    Total number of cards
