**Not random draws?**

Two things to consider

First do you know if balls 6 and 47 were the same in all draws and used in the same machine, mixed for the same amount of time, under the same environmental conditions, etc. as all these factors (and many others) are affecting the balls coming out). Most lotteries use different set of balls for drawings and they are regularly checked for uniformity (weight, roundness, rebound, etc.). This, at least, is valid for Canadian Lotto 6/49.

Second, try a little experiment. Using a coin or a random generator (for 0 for head and 1 for tail), generate a large number of coin tosses. You will be surprised how many times you will get 10 or more consecutive heads or tails. Based on that, can you conclude that the coin is rigged.

Using Excel, I generated 10 series of 5000 coin tosses. On average, for each 5000 coin toss, I got 5.7 series of 10 or more head or tails about evenly split. I even got one serie of 15 heads.
