24A geological study indicates that an exploratory oil well should strike oil with probability 0.4.(a) What is the probability that the first strike comes on the fifth well drilled? (Round your answer to three decimal places.)(b) What is the probability that the fourth strike comes on the ninth well drilled? (Round your answer to three decimal places.)(c) What assumptions did you make to obtain the answers to parts (a) and (b)? (Select all that apply.)The trials are independent.The trials are dependent.The probability of success is smaller from trial to trial.The probability of failure is smaller from trial to trial.The probability of success is the same from trial to trial.(d) Find the mean and variance of the number of wells that must be drilled if the company wants to set up three producing wells.μ =02=

(a) A small car repair company has, on average, eight customers per day. Consider the number of new customers the company gets in a week (they are open Monday - Saturday). (1) What probability model is appropriate for modelling the number of customers per week, and what value(s) should the parameter(s) have? (i) What is the probability of getting exactly 50 customers this week? (You don't need to simplify your answer.) (ii) The gap between customers (the length of time between one customer arriving and the next customer arriving) can be modelled as an exponential random variable with parameter value i = 1 hour. One customer just arrived. What is the probability of the next customer arriving in the next 30 minutes? (You don't need to simplify your answer.)
