Answer:
9/4
Step-by-step explanation:
Base on the given info we first have to use:
∴ Permutation formula ∴
[tex]\mathrm{_np_r=\frac{n!}{(n-r)!}}[/tex]
P = permutation
n = total number of objects
r = number of objects selected
Note that:
Order of which the letters are chosen is important.
Permutation Formula is which possible permutations of x elements from a set of n elements is given by.
From the given it states that five letters will be chosen from a set of nine.
Thus, now we have:
[tex]N=P_(_9_,_5_)=\frac{9!}{(9-5)!}=\frac{9!}{4!}[/tex]
Thus, the answer is 9/4
