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?
