Question 255801
<font face="Garamond" size="+2">


Since the formed number has to be even, it must end in 2, so all you need is how many ways are there to arrange the the other three digits -- three ways to select the first one times two ways to select the second one times one way to select the 3rd one.  All in all, 6.
