I have a question:

I understand that the odds of winning the PowerBall are about 1 in 175,000,000. Assuming that figure is approximately correct, then what are the approximate odds of 250,000 people choosing the correct winning number?

Any help will be appreciated Thanks

sometimes different people choose the same 'magic' number: math.stackexchange.com/questions/467575/… –  Alex Jan 21 at 2:06

1 Answer 1

Since ${250000\over 175000000}={1\over 700}$ the odds are approximately 1 in 700.

You are assuming that they choose distinct values. –  Calvin Lin Jan 21 at 15:34
Yes, it is an approximation. For a more accurate answer, the OP would need to specify more exactly how the quarter million tickets are chosen. –  Byron Schmuland Jan 21 at 16:32
