Q20. 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 20% of non-subscribing households; in other words, these households decide to subscribe. Meanwhile, 40% 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. Round the percentage to 1 decimal place, or to the nearest tenth of a percent.)
