7. Police plan to enforce speed limits by using radar traps at 4 different locationswithin the city limits. The radar traps at each of the locations A, B, C, and D areoperated 40%, 30%, 20% and 30% of the time, and if a who is speeding on his wayto work has probabilities of 0.2, 0.1, 0.5, and 0.2, respectively, of passing throughthese locations, what is the probability that he will receive a speeding ticket?

The rain gauge in different location R1, R2, R3, R4 and Rs will operate 0.45, 0.30, 0.20, 0.25 and 0.30, respectively, at a time. If rain pours in those locations has probabilities of 0.2, 0.1, 0.3, 0.2, and 0.2, respectively, what is the probability that it will operate and measure rain water?
Imagine you have three coins: one is fair, one is biased (twice as likely to be heads as tails), the third is also biased (twice as likely to be tails as heads). You pick one of the three coins at random, and flip it 20 times. How should you decide which coin you are holding, based on the results, to maximize your probability of being correct?

Students in a class like to secretly use online calculators in their quizzes. There are three such online calculators favoured amongst the students: WolframAlpha (WA), Symbolab (S), and GeoGebra (GG). A student's favourite calculator changes from quiz to quiz according to the following rules: If a student likes WA best, then it is has a 50% chance of remaining their favourite for the next quiz; 25% of becoming S for the next quiz; and 25% of becoming GG for the next quiz. If a student likes S best, then it has a 50% chance of becoming WA for the next quiz, and a 50% chance of becoming GG for the next quiz. If a student likes GG best, then it has a 33.3% chance of becoming any of the three calculators for the next quiz. For the first quiz, there are 120 who count WA as their favourite; 80 who count S as their favourite; and 50 who count GG as their favourite. What is true about the fourth quiz?

Police plan to enforce speed limits by using radar traps at four different locations within the city limits. The radar traps at each of the locations L1, L2, L3, and L4 will be operated 40%, 30%, 20%, and 30% of the time. If a person who is speeding on her way to work has probabilities of 0.2, 0.1, 0.5, and 0.2, respectively, of passing through these locations, what is the probability that she will receive a speeding ticket?
