Problem 3

On an assignment, there are two true or false questions. You have no idea what the correct answer is to either one so you guess.

How many outcomes are in the sample space for the assignment?
What is the probability that you get both of them right by guessing? Explain your answer.
What is the probability that you get exactly one of them right by guessing? Explain your answer.

Problem 7

ForLesson 6: A Special Point

Select all true statements.

The incenter of a triangle is the intersection of the angle bisectors.
The incenter is the same distance from all the vertices of the triangle.
The incenter is the same distance from all sides of the triangle.
In order to construct the incenter, all 3 angle bisectors must be constructed.
The incenter is the intersection of the perpendicular bisectors of each side.
