An office machine costs $7,500 to replace unless a mysterious, hard-to-find problem can be found and fixed. Repair calls from any service technician cost $750 each, and $3,000 is available to get this machine fixed. A repair technician has a 29% chance of fixing it. Complete parts (a) through (c) below. . . . . . (a) Create a probability model for the number of visits needed to fix the machine or exhaust the budget of $3,000. (That is, there can be at most four visits.) p(X = 1) = 0.29 p(X = 2) = p(X = 3) = p(X = 4) = p(X 2 5) = (Round to four decimal places as needed.)(b) Find the expected number of service technicians that will be called in. The expected number of technicians is 1.49 technicians. (Round to two decimal places as needed.) ((2) Find the expected amount spent on this machine. ($10,000 must be spent for a new one if a vendor does not repair the machine.) The expected amount spent on this machine is $ 3743.00 . (Round to the nearest cent as needed.)
