Question 5 (a) A secondary school claims that 60% of the parking spaces are used by male staff. A sample of 10 parking spaces was selected, nd the probability that at least 2 of 10 parking spaces are used by male staff. (b) The number of vehicles arriving a gas station for fuelling follows a distribution with rate 15 vehicles per hour. Find the probability that there will be more than one vehicle arriving the gas station in a 20-minute period. c) Assume that the number of primary school students visit the museum in a day is distributed as a Poisson random variable. The mean number of visiting in a day is 2.4. What is the probability that in any given day, if i) Fewer than two students will visit? ii) More than two students will visit
