This pattern will continue, with the number of possibilities dropping by one each time. So, it is that the third ball fitting the pattern is 1 in 47, the fourth is 1 in 46, the fifth ball is then 1 in 45 and the last ball completing the pattern is 1 in 44. To non-mathematicians, however, it seems completely illogical that it could ever follow such a pattern, despite all balls having the same chance of being drawn.
