Binomial Distribution Table: Symmetry Study the binomial distribution table (Table 2 of the Appendix). Notice that the probability of success on a single trial p
(a) Compare P(3 successes), where p = 0.30, with P(2 successes), where p = 0.70.
(b) Compare P(3 or more successes), where p = 0.30. with P(2 or fewer successes). where p = 0.70.
(c) Find the value of P(4 successes), where p = 0.30. For what value of r is P(r successes) the same using p = 0.70?
(d) What column is symmetric with the one headed by p = 0.20?

- 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_forwardProbability Distribution An experiment is described. (a) Complete the table of the probability distribution. (b) Draw a probability histogram. A jar contains five balls numbered 1, three balls numbered 2, one ball numbered 3, and one bait numbered 4. A ball is drawn at random and the number of the ball is observed.arrow_forwardDISCUSS: Most Likely Outcome for n Tosses of a Coin A balanced coin is tossed n times. In this exercise we investigate the following question: What is the number of heads that has the greatest probability of occurring? Note that for a balanced coin the probability of heads is p = 0.5. Suppose n = 8. Draw a probability histogram for the resulting binomial distribution. What number of heads has the greatest probability of occurring? If n = 100, what number of beads has the greatest probability of occurring? Suppose n = 9. Draw a probability histogram for the resulting binomial distribution. What number of heads has the greatest probability of occurring? If n = 101, what number of heads has the greatest probability of occurring?arrow_forward
