Need some help determining if there is more I have to do with this question
"A bag contains 3 red balls, 4 yellow balls, and 5 white balls. If two balls are being drawn from the bag without replacement, what is the probability that the first ball is yellow and the second ball is white?"

So I know that to calculate the probability of drawing two balls you calculate the individual probability of drawing each ball then multiply them together. But do I need to do any additional calculations for the probability that they are drawn in the correct order (first is red, second is white)? If so, what equation would I use to do that? Or am I over-thinking this?
