Understand and use the concept of conditional probability, including: understanding how conditioning affects the probability of events and finding conditional probabilities from a two-way frequency table.
Remarks
Example: In a certain large city, 25% of all wage earners have a college degree. Of those who do have a college degree, 10% earn more than $80,000 per year, and of those who do not, 4% earn more than $80,000 per year. If a randomly selected wage earner earns more than $80,000 per year, what is the probability that (s)he has a college degree?General Information
