Amie has a deck of 60 sports cards, of which some are baseball cards and some are football cards. Jamie pulls out a card randomly from the deck, records its type, and replaces it in the deck. Jamie has already recorded nine baseball cards and 11 football cards. Based on these data, what is, most likely, the number of baseball cards in the deck?

Answer:

27 is the most likely number of baseball cards in the deck

Step-by-step explanation:

9/60*3/1= 27/60

11/60*3/1=33/60

27/60+33/60=60/60

20+30=50

7+3=10

50+10=60

27 because out of 20 cards 9 are baseball. 20 is 1/3 of 60. 9x3=27
