Counterfeit dice roll question

A six sided die, faces numbered 1 - 6 as usual, is known to be counterfeit. The probability of rolling an even number is twice of the probability of rollong an odd number. What is the probability that, if the die is throw twice, the first roll will be a 5 and the second will be a 6?

A) 2/8! B) 1/18 C) 2/27 D) 1/9 E) Can not be determined from the information given.

I have not taken any probability but I figured if the dice was "fair" then there would be 3/6 chance to roll an even number and a 3/6 chance to roll an odd number.

But the probability of rolling an even number is twice that of rolling an odd number

So does this mean the probability of rolling an even number is 4/6 and the probablity of rolling an odd number is 2/6?

I am not sure how to figure out the next part if that is correct though. Can someone help?
