Answer: There are 15 sets of processors.

Step-by-step explanation:

Since we have given that

Number of processors in cluster A = 8

Number of processors in cluster B = 4

Total processors = 12

Number of failed processors in cluster A = 2

Number of failed processors in cluster B = 4

Total failed processors = 2+4 = 6

So, Not failed processors = 12-6 = 6

Number of copies = 2

So, Number of sets of processors can be used is given by

$^6C_2\\\\=15$

Hence, there are 15 sets of processors.
