# 3/4 is my answer, is it correct?

3/4 is my answer, and I came here to check if it was correct...

EDIT:

If it helps (text version):

The digits 2,3,5, and 7 are arranged randomly to form a four-digit number. What is the probability that the number is odd? Express your answer as a common fraction.

The number of possible arrangements of the digits  is 4!  = 24

Let's look at those which form even numbers.....this occurs when the "2"  appears at the end of a number

So....in that case.....the other digits can be arranged in 3!  =  6 ways

So.....there are 6 even numbers and 18 odd

So

18 / 24  =   3 / 4     and you are correct!!!!
