In Exercises 1–22, use Bayes’ theorem to calculate the probabilities.
Accident Rates An automobile insurance company has determined the accident rate (probability of having at least one accident during a year) for various age groups. (See Table 2.) Suppose that a policyholder calls in to report an accident. What is the probability that they are over 60?
Table 2
Age Group |
Proportion of Total Insured |
Accident Rate |

- these are solutions to a tutorial that was done and im a little lost. can someone please explain to me how these iterations function, for example i Do not know how each set of matrices produces a number if someine could explain how its done and provide steps it would be greatly appreciated thanks.arrow_forwardQ1) Classify the following statements as a true or false statements a.
