Waitresses all want to work the “high roller” room at a local restaurant. There are six waitresses each evening assigned to one of six rooms in the restaurant. The room assignments are made by fair random selection, such that each waitress has an equal probability of being in the “high roller” room. If a waitress in the “high roller” room will always make $200 in tips over the course of an evening while waitresses in all other rooms will make$75, over time (on average) how much can a waitress at this restaurant expect to make per evening?

$275.00$95.83

$137.50$179.17
