Take any two sheets, with C above 2 and 52 below, that is, 52*5 1/2=26*5 1.

There are four and six colors in C, each with 13* 13.

So the probability is13 *13 * 6/(26 * 51) =13/17.

There is only one red heart,

There are 13 kinds of hearts,

Just choose the remaining candidates. On c 1, on c 39.

A *** 13*39

There are two hearts in C, 13, which means 13*6.

( 13*39+ 13*6)/(26*5 1)= 15/34
