Solution

For this case we know that the total of numbers are 50 and then the player needs to select 7 out of 8 numbers to win the second prize so then in terms of probability we can do this:

[tex]p=\frac{8C7(42C1)}{50C8}[/tex]

And using properties of combinatories we got:

[tex]p=\frac{8\cdot42}{50C8}=\frac{336}{536878650}=\frac{8}{12782825}[/tex]
