Answer: 360,360
Explanation:
The number of permutations of n things of which a are identical, b are identical and so on... :-
![(n!)/(a!\ b!....)](https://img.qammunity.org/2020/formulas/mathematics/college/td5md1cea2dl8kn7tdyxmawve2xfsvkgo7.png)
Given : A clothing store has a certain shirt in 4 sizes: small, medium, large, and extra large.
If it has 2 small, 3 medium, 6 large, and 2 extra large in stock, then total shirts :
![2+3+6+2=13](https://img.qammunity.org/2020/formulas/mathematics/high-school/u24wp5i9nli81k0hccag1agkyb74pgizik.png)
Then, the number of orders in which the store can sell all the t-shirts will be :_
![(13!)/(2!3!6!2!)\\\\=(13*12*11*10*9*8*7*6!)/(2*3*2*6!*2)\\\\=360360](https://img.qammunity.org/2020/formulas/mathematics/high-school/jcenwnedq87pme9e96vp17tzqbb2xsueq0.png)
Hence, the number of orders in which the store can sell all the t-shirts = 360,360
