standard_description: Develop a probability distribution for a random variable defined for a sample space in which probabilities are assigned empirically; find the expected value. For example, find a current data distribution on the number of TV sets per household in the United States, and calculate the expected number of sets per household. How many TV sets would you expect to find in 100 randomly selected households?
problem_activity: Task
How many one-hundred dollar bills do you need to make \$2,000? \$20,000?
How many ten dollar bills do you need to make \$2,000? \$20,000?
How many dimes do you need to make \$0.20? \$2? \$20?
How many pennies do you need to make \$0.02? \$0.20? \$2?
Use the answers to the questions above to fill in the table:
{"table": [{"tbody": [{"tr": [{"td": [{"_value": "$A$"}, {"_value": "$B$"}, {"_value": "$A\\div B$"}]}, {"td": [{"_value": "2"}, {"_value": "0.01"}, {}]}, {"td": [{"_value": "20"}, {"_value": "0.1"}, {}]}, {"td": [{"_value": "200"}, {"_value": "1"}, {}]}, {"td": [{"_value": "2,000"}, {"_value": "10"}, {}]}, {"td": [{"_value": "20,000"}, {"_value": "100"}, {}]}]}]}]}
What changes (and how does it change) and what stays the same as you move from row to row down the table?
