Without having clear description in the post, I don't know what lottery means --- can only guess.
I will assume that among 39 tickets there are 5 winning:
- one for the 1st prize;
- one for the 2nd prize;
- one for the 3rd prize;
- one for the 4th prize;
- one for the 5th prize.
Then the probability to win the second prize bying one ticket is .

Good lesson to learn from this post and from my solution is THIS:
When the problem is about PROBABILITY, think about the associated probability/statistic experiment (!)
