## Money For Lunch?

In my town there are four restaurants. The price for lunch at the four restaurants is $5.00, $10.00, $15.00, and $20.00.

In my wallet I have four bills. They might be ones, fives, tens, or any combination of those (with each type of bill being equally likely) but I don't know what they are.

If I randomly select a restaurant, what is the probability I'll have enough money for lunch?
