Sales records of a hobby shop showed the following number of radio-controlled trucks sold weekly for each of the last 50 weeks. What is the probability of selling at least two trucks in any given week? Number of Trucks Sold Number of Weeks 20 1 15 10 3 4 4 1 O P{2, 3, 4} = 1/50 = 0.02 O P{2, 3, 4} = 4/50 + 1/50 = 0.10 O P{2, 3, 4} = 10/50 + 4/50 + 1/50 = 0.30 O P{2, 3, 4} = 4/50 + 10/50 = 0.28

A country has a population of 21M people. Some people received a certain treatment and some didn’t. Table 1 shows the disease rates based on age and treatment status. The treatment has no side effects, and only changes the probability that someone contracts this (undesirable) disease. Age Untreated Treated People Disease Disease per 100K People Disease Disease per 100K young 5,000,000 40 0.8 5,000,000 20 0.4 old 1,000,000 60 6.0 10,000,000 300 3.0 Table 1: Disease rates based on age and treatment status. (a) Define the following events and compute four conditional probabilities of contract- ing the disease based on a person’s age and based on their treatment status. The events are D:= contracting the disease, Y := young, O:= old, T:= treated, and U:=untreated. Note that O = Y c, and similarly for T and U. Now, calculate 4 probabilities like P(D|T, Y ) for each possibility. (b) What is the probability of contracting the disease if you are treated? Untreated? (c) Based on…
