    ok so start by thinking of the possibilities: wedding venue 1 and reception venue 1 wedding venue 1 and reception venue 2 wedding venue 1 and reception venue 3 that's 3 solutions for one given wedding venues and repeat for the other 3 wedding venues that multiplies this result by 4: 3x4 = 12 we have covered all possibilities

    If there is a rule that justifies what you are doing there then great! but its always good to be able to think it through logically if all else fails!
