Patterns in Floor Tiling A square floor is to be tiled with square tiles as shown. There are blue tiles on the main diagonals and red tiles everywhere else. In all cases, both blue and red tiles must be used. and the two diagonals must have a common blue tile at the center of the floor. If 81 blue tiles will be used, how many red tiles will be needed?

At a BBQ, you can choose to eat a burger, hotdog or pizza.  you can choose to drink water, juice or pop.  If you choose your meal at random, what is the probability that you will choose juice and a hot dog?  What is the probability that you will  not choose a burger and choose either water or pop?
