The item above is answered through the concept of Combination since the arrangement of how the magazines are to be chosen from the total number of magazines given is not a factor. The mathematical expression for this combination is,

n = 17C4

or "combination of 17 taken 4.

n = (17!) / (4!) (17-4) !

n = 2380

Answer: 2,380
