[Q20 - Q21] A utility prоvider clаssifies eаch hоusehоld into low, medium, аnd high based on its daily energy usage. The thresholds for categorization is as follows: 0 - 20 kWh: low 20 - 40 kWh: medium 40 kWh or higher: high The company offers different prices according to the household category as follows: low: 12 cents/kWh medium: 15 cents/kWh high: 20 cents/kWh Suppose the probability a randomly selected household belongs in low, medium, and high categories are 0.3, 0.6, and 0.1, respectively. Given that it belongs in the low or medium category, the household's electricity usage is uniformly distributed within the range (e.g., if low, uniformly between 0 and 20 kWh). If it belongs in the high category, it is uniformly distributed between 40 and 80 kWh. Show your work on the scratch paper answering Q20 - Q21.
