Solution: Solve according to the properties of classical concepts , permutations , combinations and probability . Suppose event 

the designated person does not get spades or spades ,

Then the person designated by

gets both of spades and of spades .

　　A deck of playing cards ( cards) is dealt to people. The person picks cards from the cards, the person picks cards from the remaining cards, and the person picks cards from the remaining cards. , the remaining cards are given to the person, and there are a total of

ways to divide them. The designated person gets the of Spades and the of Spades at the same time : This person first gets of Spades and of Spades, and then randomly picks cards from the other cards ; the other people divide the remaining cards into equal parts , that is, there is

method, so 

,

Therefore, property 3 of probability has

.
