According to the Canadian Animal Health Institute, 58% of households have at least one pet (dog or cat). Suppose you're a mailperson delivering mail on a street with 6 households.

a) What is the probability that none of the households have at least one pet? (0.5 marks)

b) What is the probability that exactly 2 of the households have at least one pet? (0.5 marks)

c) Assume 1% of pets bite the mailperson. What is the probability that delivering to one house will result in an animal bite?
