Ok here is the problem

Lets think of this in terms of horse racing...

If you have

8 selections that have odds of 35/1

9 selections that have odds of 17/1

2 selections that have odds of 11/1

1 selection that has odds of 8/1

What amount must you wager on each horse to earn a profit every single time? Is it possible? I am not good with math at all. Any help would be much appreciated. Thanks in advance
