"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."
"In a group, 40% of the items are red. Of all the red items in the group, 30% also have stripes. What percentage of the items in the group are red and have stripes?"

What you'll learn
- Find the probability of an event built from two events with "and", "or" and "not", from a two-way table, an area model or a description of a situation, choosing the route to P(A and B) by what is given
- Express "or", "neither", "at least one" and "exactly one" as sums of the four regions two events create, or as complements, and compute each
- Complete a table of probabilities from P(A), P(B) and either P(A and B) or P(A or B)
- Compute P(A and B) as P(A) × P(B | A) from a two-stage description, and fill the four regions when both stages are given
- Decide whether two events are independent, and use P(A and B) = P(A) × P(B) only when they are
