Grade 10 Represent and Determine Probability CCSS: HSS-CP.B.8
A regular set of billiard balls has 15 balls, with the numbers 1-15 on them. The first eight balls (1-8) are solid, and are the colors yellow, blue, red, purple, orange, green, maroon, and black respectively. The next seven balls (9-15) are striped (white with a stripe of color), the colors being the same as for the solid (9 being yellow striped, 10 being blue striped, etc), but no black. If there is a set of billiard balls in a box, what is the probability that you pick out a blue ball, given that it is a striped ball?
