    The way you figure this out is that the first person picked has a 1/8 chance, the second would be 1/7 (one person already went) and the third person would have a 1/6 chance (two people already went). To find the probability of this happening would be all the odds multiplied together, so (1/8) * (1/7) * (1/6) which equals 1/336
