"Use one- and two-way tables, area models, and other representations to find relative frequency, probabilities, and conditional probabilities."
"• Calculate, express, or interpret the probability or conditional probability of an event using a data display showing frequencies for a single variable, a two-way table, an area model, or a description of a situation. Infrequently, given a probability, determine an unknown number in a data display showing frequencies for a single variable, a two-way table, or a description of a situation, including using a probability to determine the frequency of an event."

What you'll learn
- Define conditional probability and interpret the notation P(A|B) as "the probability of A given that B has occurred"
- Calculate conditional probability using P(A|B) = P(A and B) / P(B)
- Read conditional probabilities directly from two-way frequency tables by restricting to the appropriate row or column
- Correctly distinguish between P(A|B) and P(B|A) and explain why they are generally not equal
- Use a given conditional probability to find an unknown count in a table
