Break a stick of unit length at a uniformly chosen random point. Then take the shorted of the two pieces and break it again in two pieces at a uniformly chosen random point. Let X denote the shortest of the final three pieces. Find the density of X.

A point is chosen uniformly at random from a disk of radius 1, centered at the origin. Let R be the distance of the point from the origin, and Θ the angle, measured in radians, counterclockwise with respect to the x-axis, of the line connecting the origin to the point. 1. Find the joint distribution function of (R,Θ); i.e. find F(r,θ) = P(R ≤ r, Θ ≤ θ). 2. Are R and Θ independent? Explain your answer.

Consider a stick of unit length, broken into 3 pieces using the following methods: 1. We chose randomly and independently two points on the stick using a uniform PDF, and we break stick at these 2 points 2. We break the stick at a random point chosen by using a uniform PDF, and then we break the piece that contains the right end of the stick, at a random point chosen by using a uniform PDF 3. We break the...

Suppose you have a reed of length 1 unit. If you haphazardly break this reed twice (forming 3 pieces), those 3 pieces might form a triangle, or they might not. What is the empirical probability that you can form a triangle from the pieces? Estimate this by “breaking” 2000 reeds twice and seeing if the parts form triangles.
