Suppose that 170,000 couples married last year in Texas.(a) Approximate the probability that in at least one couple, both partners sharea birthday on January 12th. (Hint: treat each couple as a “trial” and use a Poissondist.)(b) Approximate the probability that in at least one of these couples, bothpartners have their birthdays in the same month.

Nissa is randomly pulling the medical records of a hospital's patients and collecting the records of those who have multiple stays at this hospital. Assume that 27% of all patients who have ever stayed at this hospital have multiple stays. What is the probability that the first multiple stays patient record that Nissa comes across is the fourth one she pulls? Use a TI-83, TI-83 Plus, or TI-84 calculator to find the probability. • Round your answer to three decimal places.
The probability that an applicant will be approved for a mortgage is 0.15. Each applicant has the same probability of being approved and the event that they are approved are independent.
