- QUIZ 1.11 (design matlab program and explain in detail)

• #03, due to Oct. 2 (Wed.) before the class starts.(download)

• #04 <Monty Hall problem>

• #05 <Broken stick problem> due to Nov. 5 (Tu.) before the class starts.

• Consider a stick of length 1 meter. Two points are chosen randomly and uniformly on the stick

• and then the stick is broken into three pieces, at those cut points.

• What is the probability that the three pieces can be used to construct a triangle?

• #06 <Variance> Calculate the variances for Geometric, Binomial, and Poisson pmf (probability mass function). - You can find the answers in the Note p67 ~ 89.
