1.The Census Bureau reports that 55% of all 3-to-5-year-old children attended preschool programs at least a portion of the day. If 18 children are chosen at random, what is the probability that fewer than six children attend such a program?
2. Experimenters in ecology found that the average density of zooplankton in a pond where predators had been introduced was 4.60 individuals per centiliter. Assume a Poisson distribution applies. What is the probability that a centiliter of fluid from the pond contains no individuals?
The problem below outlines the process of finding the probability of an event given a particular distribution (Binomial and Poisson)
