Solution: The existing four playing cards are hearts, clubs, diamonds and spades. They are exactly the same except for the color. After washing, buckle it on the table. Three people, A, B and C, randomly draw a card in turn, and they will return immediately after drawing.

∴ * * The same possible result: 4×4×4=64 (species),

There are four situations when three people draw the same color.

∴P (the colors drawn by three people are the same) = 4/64 =116;

There are 24 situations in which three people draw different colors.

∴P (three people draw different colors) = 24/64 = 3/8;

∫ There are 36 situations in which the colors painted by three people are the same as those painted by two people.

∴P (two people draw the same color) =36/64=9/ 16.
