13) Paul wants to build triangular patios for his back yard. He is not sure what measurements
he can use to build his patio so he decides to come up with some numbers and just starts
building. The sets of measurements he wants to use for the patios are …
Patio #1  12ft, 13 ft, and 1ft
Patio #2  120 degrees, 53 degrees, and 37 degrees
Patio #3  90 degrees, 45 degrees, and 45 degrees
Patio #4  10ft, 12ft, and 3ft
Which set of measurements create triangles?
Probability and Statistics:

a) What is the probability of spinning black and 2?
b) What is the probability of spinning an even number and gray?
c) What is the probability of spinning a number less than 6 and white?
