The 1 in 14 million number is for 1 - 49. For 1 - 50 the odds are slightly worse; 1 in 15,890,700.

Even if it's 1 - 45, the odds are still 1 in 8,145,060, so I don't know how he could figure 1 in 4 million. Maybe they don't use the typical pingpong ball system.

For those that want to play along at home, for numbers 1 - 49, the odds against any particular combination are:

49/6 x 48/5 x 47/4 x 46/3 x 45/2 x 44/1 = 13,983,816
