How many different possible arrangements can be obtained from the letters G, M, A, T, I, I, and T, such that there is at least one character between both I's? Choose the most appropriate option:
A) 360
B) 720
C) 900
D) 1800
E) 5040
A= all possible permutations = 7!/2!2!   B= permutations with II together = 6!/2!   A-B = 900   ANSWER:900
