- Calculate the coefficient of x7y5zx7y5z in (x+y+z)13(x+y+z)13. (b) In her discrete math class, Karen was asked to count the number of four-person teams that could be formed from a group of 17 males and 13 females with at least one male and at least one female. They mistakenly argue as follows: There are 17 choices for a male on the team and 13 choices for a female on the team. After that, there are (282)(282) to choose the remaining two players from the remaining 28 individuals. Therefore, by the rule of product, there are 17⋅13⋅ (28⋅27)/2 different teams. i. Explain the error in Karen's reasoning. ii. Determine the correct number of four-person teams that can be formed with at least one male and at least one female. (You may leave your answer in terms of unsimplified binomial coefficients.)A new warehouse is being designed and a decision concerning the number of loading docks is required. There are two models based on truckarrival assumptions for the use of this warehouse, given that loading a truck requires 1 hour. Using the first model, we assume that the warehouse could be serviced by one of the many thousands of independent truckers who arrive randomly to obtain a load for delivery. It is known that, on average, 1 of these trucks would arrive each hour. For the second model, assume that the company hires a fleet of 10 trucks that are assigned full time to shipments from this warehouse. Under that assumption the trucks would arrive randomly, but the probability of any truck arriving during a given hour is 0.1. Obtain the appropriate probability distribution for each of these assumptions and compare the results.The nAChR ion channel can be in one of three states: resting (R), closed with Ach bound (C), and open (O) with transition probabilities (per one microsecond): 0.04 (from R to C), 0.07 (from C to R), 0.12 (from C to O) and 0.02 (from O to C); the other transition probabilities are 0. Calculate the probability of the following string of states: OCCR, taking the first state as given. (Enter three digits after the decimal).
