Ensure you show all formulas and state values of variables, substitute and solve. Provide a concluding statement for all parts. Suppose that 31% of families in town own iPads. If sixteen families are surveyed at random, Determine the probability that exactly 4 families own an IPAD. (3 marks) Determine the probability that less than 3 families own iPads. (3 marks) Determine the probability that least 3 families own iPads. (3 marks) Determine the expected number of families with an iPad. (2 marks) There are ten cats and eleven dogs in a pet shop. Nine pets are chosen at random to visit a children’s hospital. Determine the probability that exactly three of the pets will be dogs. (3 marks) Determine the probability that less than 2 of the pets will be dogs. (3 marks) Determine the probability that at least 2 of the pets will be dogs. (3 marks) Determine the expected number of dogs chosen. (2 marks) Determine the probability that less than 3 families own iPads. (3 marks) Determine the probability that least 3 families own iPads. (3 marks) Determine the expected number of families with an iPad. (2 marks)
