Four automatic insertion machines are set up in series to add components to printed circuit boards. Each machine inserts 20 different component types. Due to board design and component requirements, automatic setup and insertion times for machines are uniformly distributed with a mean of 4 minutes and a coefficient of variation of 0.5. Assume machines do not fail. Estimate the production rate per hour if buffers of size 2 are added between each pair of machines. Round answers to 1 decimal place.

The following table shows the probability that one diagnosed epileptic patient has seizures in one week. Based on previous research, the probability related to its occurrences are tabulated below: Let S(severe) be the event that there are at least 3 seizures in one week and let M(mild) be the event that there are less than 2 seizures in one week. Find the probabilities P(S) and P(M). Number of Seizures Probability 0 0.02 1 0.62 2 0.18 3 0.10 4 0.08
