Use the Poisson distribution to find the indicated probabilities World War II Bombs In Exercise we noted that in analyzing hits by V-l buzz bombs in World War II, South London was partitioned into 576 regions, each with an area of 0.25 km2 . A total of 535 bombs hit the combined area of 576 regions. a. Find the probability that a randomly selected region had exactly 2 hits. b. Among the 576 regions, find the expected number of regions with exactly 2 hits. c. How does the result from part (b) compare to this actual result: There were 93 regions that had exactly 2 hits? Exercise Notation In analyzing hits by V-l buzz bombs in World War II, South London was partitioned into 576 regions, each with an area of 0.25 km2 . A total of 535 bombs hit the combined area of 576 regions. Assume that we want to find the probability that a randomly selected region had exactly two hits. In applying Formula 5-9, identify the values of µ, x, and e. Also, briefly describe what each of those symbols represents.

A variable of a finite population takes values 5, 7, or 8 and has the following frequency distribution:     5 7 8 frequency 25 40 60 Construct a probability histogram for variable X.

Determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. The time required to download a file from the Internet b. The height of a randomly selected giraffe c. The eye color of people on commercial aircraft flights d. The number of free-throw attempts before the first shot is made e. The amount of rain in City B during April f. The number of hits to a website in a day a. Is the time required to download a file from the Internet a discrete random variable, a continuous random variable, or not a random variable? A. It is a discrete random variable. B. It is a continuous random variable. C. It is not a random variable. b. Is the height of a randomly selected giraffe a discrete random variable, a continuous random variable, or not a random variable? A. It is a discrete random variable. B. It is a continuous random variable. C. It is not a random variable c. Is the eye color of people on commercial aircraft flights a discrete random…

Part a through c please.

College students were given three choices of pizza toppings and asked to choose one favorite. Results are shown in the table. toppings freshman sophomore junior senior cheese 23 18 10 18 meat veggie 10 24 10 OA. 227 B. 408 O C. 677 OD. 421 10 18 10 10 24 Estimate the probability that a randomly selected student who is a junior or senior prefers veggie. Round the answer to the nearest thousandth. ***

A box contains many tickets, with an average value of 50 and an SD of 10. If we draw 150 times with replacement from the box and keep track of the sum of draws, what is the approximate chance that the sum of draws is smaller than 7400? Choose the answer that is closest.

. A sample of 200 people was asked their favorite genre of music. Below are the results. Gender Rock Pop Hip-Hop Other Male 31 20 37 12 Female 17 30 19 34   If one of those people is randomly selected, find the probability that the person is a female or their favorite genre of music is Hip-hop. Round to three decimal places as needed. If one of those people is random selected, find the probability that the person’s favorite genre of music is Pop, given that the person is a male. Round to three decimal places as needed.
