Abia is one of three servers who work at a restaurant that is open from tuesday to sunday.

Every week the servers randomly draw slips of paper from a hat to decide which two days they won't have to work, in addition to monday.
What is the conditional probability that Abia will draw a second weekend day, given that her first draw was a weekend day?
I did (2/6)(1/5) and that's 1/15 but the answer is 1/20. Please help!!!!
