- Question 14 Suppose you roll a special 34-sided die. What is the probability that the number rolled is a "1" OR a "2"? Submit Question ete 24 96 3. 7. 9. darrow_forwardThe well-known geyser "Old Faithful" has a very predictable schedule for when it erupts. However, for the nearby Beehive Geyser, the eruptions occur at random times. In trying to provide visitors information on their chances of seeing Beehive Geyser erupt, park officials have recorded eruptions over the past 265 days. During this period, there were 162 eruptions. Suppose that we randomly select a day in the future. Using the data from the park officials and assuming that the number of eruptions follows a Poisson distribution, what are the mean and standard deviation of the number of eruptions that occur over the day selected? Round your answers to two decimal places. (a) mean: 0.611 ? (b) standard deviation: 0.782arrow_forwardA randomly selected person has a birthday in April ?arrow_forward

There are 400,000 residents in a certain city within this state. a) Use a suitable approximation to find the probability that there will be 3 or more suicides in the city in a given month. Assume independence between residents of the city. b) Find the probability that there will be at least 2 months during the year with 3 or more suicides in the city. Assume independence between months of the year.arrow_forward
