Nominal distribution, Poisson distribution, Uniform distribution, or Exponential

Question

Nominal distribution, Poisson distribution, Uniform distribution, or Exponential distribution?

1.It was believed that the probability of being hit by lightning is the same during the course of a thunderstorm. Which of the following distributions would you use to determine the probability of being hit by lightning during the first half of a thunderstorm?

2.Suppose the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes. Which of the following distributions would you use to determine the probability that a defective light bulb will be produced in a 15-minute interval?

3.Suppose the probability of finding a defective spot in an area on a piece of glass is the ratio of that area to the total area of the glass and the probability is the same across the whole glass. Which of the following distributions would you use to determine the probability of finding a defective spot in a randomly selected one square inch area on a piece of 10 feet by 10 feet glass?

Explanation / Answer

1. Uniform distribution since the probability of being hit by lightning is the same during the course of a thunderstorm

2. Exponential distribution can be used to determine the probability that a defective light bulb will be produced in a 15-minute interval

3. Uniform distribution is used in this case
