probability question

Question

In a new California lottery game, contestants pick 5 numbers (1-9 inclusive) and must guess exactly three correct in order to win. What’s the probability of winning this lottery?

Answer 1

The answer depends on whether the numbers picked can be repeated and whether the guess can have repeat numbers.

For example could you have 5 9's selected or must the 5 numbers all be different?

Then can you guess 3 3's or must the guess all be different.

In order to answer the question you must specify these choices.
