Hi, This is a puzzle for all you probability experts. I think I can find the answer but wanted additional perspectives. I noticed something that seemed a little strange in our lottery results. Several times I noticed that the same number (out of six) was drawn at the same spot in the sequence (eg 3rd out of six), 2 weeks in a row. That didn't trigger my concern until this week I noticed that the last 2 numbers drawn were identical to those in last week's draw (and in the same order). It's like they forgot to draw the last two and just left the ones from last week... So, the question is: what's the probability of occurrence of 2 numbers out of 6 being identical, and in the same positions, 2 weeks in a row? The draw involves the numbers 1-45 inclusive. Do the positions in the sequence where the above occurs matter? Ie is it more striking that it occurred on the last 2? Thanks for your thoughts.
