Fuck the lotto 30 chances no winers

 

Well there's roughly a 0.97 chance of someone getting the numbers right so it's quite likely

Only a 36.6% chance no one wins though when there are 33 entrants. So 63.4% chance there should have been at least one winner.

Ok so 30 numbers from 1000.

 

Chance of hitting zero numbers is (30 C 0) (970 C 30) / (1000 C 30).

 

Which is [ (970!) / (940! 30!) ] / [ (1000!) / (970! 30!) ].

 

Cancelling common factors we have (970 x 969 x 968 x ... x 941) / (1000 x 999 x 998 x ... x 971).

 

Which is 39.55%.

 

Odds of that happening to all 33 people are 0.3955^33, or 0.0000000000051%

 

Mind blown @boubabi
