Javier volunteers in community events each month. He does not do more than five events in a month. He attends exactly five events 35% of the time, four events 25% of the time, three events 15% of the time, two events 15% of the time, one event 5% of the time, and no events 5% of the time.
Find the probability that Javier volunteers for less than three events each month. (Enter an exact number as an integer, fraction, or decimal)
The chance of an IRS audit for a tax return with over $25,000 in income is about 2% per year. Suppose that 100 people with tax returns over $25,000 are randomly picked. We are interested in the number of people audited in one year. Use a Poisson distribution to answer the following questions.
Give the distribution of X. (Enter an exact number as an integer, fraction, or decimal.)
