    On your turn, you roll twice in the game of Monopoly. Determine the odds in favour of rolling doubles with a pair of dice on your first or second roll.

    This question is worth 4 marks...but I don't see why? Is it really complicated?

    Number of combinations: 6x6=36
    Number of "doubles" combinations: 6

    Therefore the odds are 6:30=1:5 on your first or second roll.

    Where I see a possible complication is in the "first or second roll"...is this question asking the odds when you roll twice, or is it treating each roll differently...like the odds of rolling doubles on the first try is 1:5 and the odds of rolling doubles on the second try is 1:5. what i'm asking is if my answer is correct? and if I need to combine these two odds together somehow?

    I think the question is the following. Take a pair of dice, and roll them both. Then roll them both again. What are the odds of having got doubles on either the first roll or the second (or both)?

    it says in a turn you roll twice.
    it then says : determine the odds in favour of rolling doubles with a pair of dice on your first or second roll.
    I think it means 1st and 2nd roll in the same turn.

    I wouldn't worry about that kind of thing though because in the exam they will make it totally clear.
