From the set of numbers {p, t, u, v, w, x, y, z}, how many different combinations can we have without the t in them? Ex:. (x,y), (x), (w,z,y,x), etc... and note that (x,y)=(y,x)	Choose the correct choice from the following answers:
A) 32	B) 63	C) 64	D) 127	E) 128
Any letter (p, u, v, w, x, y, z) can be included or not.   Thus there are 2^7 combinations - 1 empty combination = 127 combinations   The answer is 127.
