Question

#1) Your company's new series "Avocado Comedy Hour" has been a complete flop, with viewership continuously declining at a rate of 31% per month. Use a suitable density function to calculate the probability that a randomly chosen viewer will be lost sometime in the next four months. (Round your answer to four decimal places.)

#2) X has a normal distribution with the given mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.)

μ = 40, σ = 20, find P(30 ≤ X ≤ 42)

Please answer both thank you

Answer 1

1)

Here we nedd to use exponential distribution with parameter . Here we need to find the probability that there is viewership loss in next four months so required probability is

Answer: 0.7106
