In the figure below, what is the ratio of the combined area of the two small circles to the larger circle?

*Solution to yesterday’s problem*

If 8 ties are striped red and blue, then 20-8=12 ties must be red or blue. Since there is an equal number of each color, 6 ties must be plain red. The probability of picking one of these 6 ties out of 20 total ties is 6/20, or *3/10*.
