The numbers 1-10 are placed on cards, and the cards are put in a hat. If two cards are drawn, in order, without replacement, what is the probability that one number is even and the other a prime?

I know there are 4 primes-2,3,5,7 and 5 even numbers 2,4,6,8,10

not sure how to figure the probability
