In a certain population of mussels (Mytilus edulis), 80% of the individuals are infected with an intestinal parasite. A marine biologist plans to examine 100 randomly chosen mussels from the population. a) Find the probability that 85% or more of the sampled mussels will be infected using normal approximati to binomial distribution. b) What is the expected number of infected mussels in 50 randomly chosen mussels?
