The chance of an IRS audit for a tax return with over $25,000 in income is about 2% per year. We are interested in the expected number of audits a person with that income has in a 16-year period. Assume each year is independent. Part (a) Part (b) List the values that X may take on. X=0, 1, 2,..., 15, 16 OX= 1, 2, 3, OX= 1, 2, 3, OX=1,2,3,... 15, 16 98, 99, 100 Part (c) Give the distribution of X X-B 0.02 □ Part (d) How many audits are expected in a 16-year period? (Round your answer to two decimal places.) 0.32 audits Part (e) Find the probability that a person is not audited at all. (Round your answer to four decimal places.) Part (1) Find the probability that a person is audited more than twice. (Round your answer to four decimal places.)

Here is the probability model for the blood type of a randomly chosen person in the United States. Blood type O A B AB Probability 0.53 0.22 0.06 0.19 What is the probability that a randomly chosen American does not have type O blood? ______________% Round to the nearest 0.01%

Subject- Statistics and Probability Instruct. The random variable X represents the number of defective bulbs when 3 bulbs are tested. The probability distribution is shown below.  X                0                1                2                  3 P(x)              0.95             0.03             0.01                0,01 Now, find the probability of at least 1 found defective.

If the probability distribution for the random variable X is given in the table, what is the expected value of X? Xi - 5 1 5 Pi .3 .5 .2 LO

Fill in the P(X=x) values to give a legitimate probability distribution for the discrete random variable X, whose possible values are -4,-2,3,5, and 6.

Do you carpool? Let  X  represent the number of occupants in a randomly chosen car on a certain stretch of highway during morning commute hours. A survey of cars showed that the probability distribution of  X  is as follows. x 1 2 3 4 5 Px 0.68 0.14 0.08 0.02 0.08 Send data to Excel   Part 1 of 7     (a) Find  P1 .
