125% Math 119-Elementary Statistics 3. The IRS compiles data on income tax returns and summarizes its findings in Statistics of Income. The table shows a frequency distribution for adjusted gross income (AGI) from federal individual income tax returns. AGI Under $10K $10K-under $20K $20K-under $30K $30K-under $40K $40K-under $50K $50K-under $100K $100K & over iv. V. Frequency (1000s) Event Probability A 26,268 22,778 18,610 14,554 11,087 30,926 18,227 142,450 4. Refer to the above table to define the following events. Name: A federal individual income tax return is selected at random. a. Compute the probability of each of the events. b. Determine the probability of P(4), the probability that the return selected shows an AGI under $10K. c. Find the probability that the return selected shows an AGI between $30K and $100K (i.e. at least $30K but less than $100K). a. Compute the probabilities of the four events. b. Find the probability of the following: i. (HOD) ii. (HUK) (1H) (JK) (KJ) B с D c. Determine if the events are mutually exclusive? i. Hand / ii. I and K E F G H= event the return shows an AGI between $20K and $100K /= event the return shows an AGI of less than $50K J-event the return shows an AGI of less than $100K K-event the return shows an AGI of at least $50K
