Hi There. I would very much appreciate help in solving this problem. Thanking you.

In a hat there are 2x R100 bills, 4x R50 bills, 5 x R20 bills and 9 x R10 bills. Two bills are drawn from the hat. What is the probability that the sum of the bills is less than R100?

:confused:

We'll be glad to help! But first, we'll need to see what you've tried and where you're getting stuck. For instance, what did you do about finding the ways that two bills would add to R100 or more?

So please reply with that information. Thank you! ;)
