You mean there are at least 1 card in each suit among the six cards drawn. This means that there are two colors, each color 1, and two other colors, each color 2. There are six kinds of this color combination, C (4 4,2) =. So, the probability of asking is

C(4，2)C( 12，2)C( 12，2)C( 12， 1)C( 12， 1)/C(48，6)

= 3763584/ 1227 15 12

≈ 0.3067

= 30.67%。
