Probability of win in a 54/6 lottery. Each number from 1 to 54 will appear at ramdom 4 times in 40 tickets?

Answer 1

I'm not sure what the second half of your question means. But your chances of winning a 54/6 lottery (meaning pick 6 from 54) is 1 / C(54, 6), where C(54, 6) is read as "54 choose 6," and is equal to 54!/6!(54 - 6)! = 54!/6!48! = 25827165. So your chances of winning are 1:25827165 = 0.000004%.
