w=7458
Answer:
18564
Step-by-step explanation:
In the problem Given, we just need to see t any 6, the order of selection does not matter, hence, this is a combination problem :
Using the combination relation :
nCr = 18C6
Recall ;
nCr = n! / (n-r)!r!
18C6 = 18! / (18-6)!6!
18C6 = 18! / 12!6! = (18*17*16*15*14*13) / (6*5*4*3*2*1)
18C6 = 13366080 / 6!
18C6 = 18564
