## anonymous one year ago Cards if 2 cards are selected from a standard deck of 52 cards without replacement, find these probabilities. A. Both are spades B. Both are the same unit C. Both are kings I know the answers (they are in the back of the book) but I need to know how to solve the problem. The answer for "a" is 1/17. For B its 4/17 and the answer for c is 1/121

A. $P=\frac{ 13 }{ 52 }\times \frac{ 12 }{ 51 }=?$

B. $P=4 \times \frac{ 13 }{ 52 }\times \frac{ 12 }{ 51 }=?$

$P=\frac{ 4 }{ 52 }\times \frac{ 3 }{ 51 }=?$
