Binomial, Negative Binomial and Hypergeometric Distribution
You are tracking the progression of category 3 hurricanes and are interested in knowing how many of these are upgraded to category 4 hurricanes. Past data indicates that category 3 hurricanes have a probability of 0.01 of being upgraded to a category 4 hurricane. Assume that these probabilities continue to represent future hurricane behavior. Assume that, due to advances in hurricane forecasting technology, meteorologists know that there will be 538 category 3 hurricanes during this year’s hurricane season. You want to use this information to predict the behavior of these hurricanes during this year’s hurricane season. Use this information to answer questions 1 to 5.
1. What is the expected number of category 3 hurricanes upgraded to category 4 hurricanes based on the data, assuming meteorologists’ predictions of the number of category 3 hurricanes are correct (round to 2 digits)?
2. What is the probability that there are exactly three category 3 hurricanes that will be upgraded to category 4 hurricanes this hurricane season? (use 3 decimal places)
3. What is the probability that more than two category 3 hurricanes will be upgraded to category 4 hurricanes this hurricane season? (Use 3 decimal places)
4. Fast forward into the future as the year’s hurricane season unfolds and category 3 hurricanes occur one at a time. What is the probability that the first hurricane that is upgraded to a category 4 hurricane is the 28th category 3 hurricane of the season? (use 4 decimal places)
5. How many category 3 hurricanes would you expect to occur before one is upgraded to a category 4 hurricane for the first time?
1,2,3 will be solved using binomial distribution and 4,5 using negative binomial.

For the past 102 years, a certain state suffered 25 direct hits from major (category 3 to 5) hurricanes. Assume that this was typical and the number of hits per year follows a Poisson distribution. Complete parts (a) through (d). (a) What is the probability that the state will not be hit by any major hurricanes in a single year? The probability is nothing. (Round to four decimal places as needed.) (b) What is the probability that the state will...
9. Assume that a procedure yields a binomial distribution with a trial repeated n times. Use (1 point) the binomial probability formula to find the probability of x successes given the probability p of success on a single trial. Round to three decimal places. n=64, x=3, p=0.04 O 0.091 O 0.139 O 0.221 O 0.375 6. Find the indicated probability. (1 point) An archer is able to hit the bull's-eye 53% of the time.
