If the magician is not using a trick deck of cards, what is the possibility that he will draw a Jack or Diamond from a very well-shuffled deck of cards?  Choose the correct choice from the following choices: A) 1 in 13 B) 4 in 13 C) 1 in 4 D) 4 in 52 E) 4 in 12
This problem uses the principle of adding fractions with a common denominator. Add the number of suits in the deck to the number of cards in each suit in the deck. Use the denominator of number of cards total in the deck. (4/52 + 13/52 = 17/52). Now subtract the number of Jacks of Diamonds in the deck from you answer. (17/52 - 1/52 = 16/52). Further reduce this fraction. (16/52 = 4/13). Answer is 4 in 13.
