- Unemployment In 2015, there were approximately 8.3 million unemployed workers in the United States. The circle graph shows the age profile of these unemployed workers. Ages of Unemployed Workers (a) Estimate the number of unemployed workers in the 16-19 age group. (b) What is the probability that a person selected at random from the population of unemployed workers is in the 20-24 age group? (c) What is the probability that a person selected at random from the population of unemployed workers is in the 25-54 age group? (d) What is the probability that a person selected at random from the population of unemployed workers is 55 or older?arrow_forwardYeast cells The famous statistician William Gosset, who worked for Guinness brewery in Ireland, took measurements of the number of yeast cells per square in a hemocytometer.Source: Statistical Methods in Biology. The data can be closely described by a Poisson distribution with a=4.68. Find probabilities of each of the following events. a. Fewer than 3 yeast cells b. Exactly 3 yeast cells c. At least 3 yeast cellsarrow_forward
