Answer:

560

Step-by-step explanation:

The best way to do this is to write it out, but with large ones like this you should use the equation:

C(n,r) = n!/(r!(n-r)!),

where:

C(n,r) is the number of combinations;

n is the total number of elements in the set; and

r is the number of elements you choose from this set.
