Suppose, you are attending an exam where there are 9 multiple choice questions with 3 options in each. A question can have multiple correct answers, and in that case, you
have to check all of the correct answers to get the question right.
a. What is the probability that you’ll get exactly 6 of the questions right?
b. What is the probability that you’ll get at most 6 of the questions right?

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
