    Wink Double or Nothing?

    Ok here's my question:

    If a soccer team has a 1 in 10 chance of winning the league and a 1 in 20 chance of winning the cup, what is the probability of this team "doing the double"?

    I think the answer is 1/200, but I would just like to clarify this with you, and would like to know how you came to your answer?

    Any help from you would be really appreciated. Thank you.

    You think right.

    Assuming that the two events are independent, you just multiply the probabilities.

    Thanks for clarifying almighty one.

    That was what I was confused about, whether the two are independant. If they weren't how would you solve the answer?
