haha, what are the odds of that?
Kinda interesting. A 30 card deck, 4 of them in hand and not part of the mulligan, so 26 to choose from. So to get the same draw in any pattern would be 4/26*3/25*2/24*1/23 = 0.00006689, or 1 in 14,950.
But they came out in the exact same pattern. He's got 1 of each of those cards within the 30, so the odds on the face of it for the same 4 in any combination is 1/26*1/25*1/24*1/23 = 0.000002787, or 1 in 358,800.
I think that math is right.
