A popular app, Zolo, has come on the market for streaming pet-friendly music while others in the household are away from home for work or errands. Every month, the app attracts 30% of non-subscribing households; in other words, these households decide to subscribe. Meanwhile, 70% of already subscribing households decide to unsubscribe each month. Suppose 20% of households are current subscribers. Using the probabilities and states as described, what percentage of households will likely be subscribers two months from now? (Enter numerical value only. Do not enter % sign. Ro

According to the Chronicles of Contrived Statistics (March, 2016), the probability that scientists from Area 51 will begin selling pet aliens in the next month is 38%. The probability that either Elon Musk will offer you a free trip to space or that scientists will begin sales of pet aliens next month is 59%. Finally, they list that probability of both happening in the next month is 25%. What is the probability that Elon Musk will offer you a free trip into space in the next month?

The Business School at State University currently has three parking lots, each containing 155 spaces. Two hundred faculty members have been assigned to each lot. On a peak day, an average of 70% of all lot 1 parking sticker holders show up, an average of 72% of all lot 2 parking sticker holders show up, and an average of 74% of all lot 3 parking sticker holders show up. a. Given the current situation, estimate the probability that on a peak day, at least one faculty member with a sticker will be unable to find a spot. Assume that the number who show up at each lot is independent of the number who show up at the other two lots. Compare two situations: (1) each person can park only in the lot assigned to him or her, and (2) each person can park in any of the lots (pooling). (Hint: Use the RISKBINOMIAL function.) If needed, round your answer to a whole percentage and if your answer is zero, enter "0". No pooling: Pooling: 51.4 % 83.8 % b. Now suppose the numbers of people who show up at…
