7. A deck of cards has a total of 52 cards (excluding the two jokers). The cards are dealt to 4 people, with each person receiving 13 cards. How many different ways can one person receive 13 cards that include all four suits? (Express the answer using combinations)


7. The total number of ways to choose 13 cards from 52 cards is $C_{52}^{13}$, then the number of ways to be missing one suit is $C_{39}^{13}$; the number of ways to be missing two suits is $C_{26}^{13}$; the number of ways to be missing three suits is $C_{13}^{13}$.
By the principle of inclusion-exclusion, the result is: $C_{52}^{13}-C_{4}^{1} C_{39}^{13}+C_{4}^{2} C_{26}^{13}-C_{4}^{3} C_{13}^{13}$.
