How many 5digit even numbers can be made using the digits 2, 4, 6, 7, and 8, if digits cannot be repeated?

none. You only show 4 even digits.

Vincent  you don't read very carefully. Steve said that you only show 4 even digits.

Actually, I was in error in my answer. Only the last digit has to be even!!
So, there are
4*4*3*2*1 = 96 choices.
Sorry, my bad.
