Using the combination formula, it is found that the photographs can be chosen in 5005 ways.

The order in which the photographs are chosen is not important, hence, the <u>combination formula</u> is used to solve this question.

Combination formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem, 6 photographs are chosen from a set of 15, hence:

C_{15,6} = \frac{15!}{6!9!} = 5005

The photographs can be chosen in 5005 ways.
