SAT probability is nearly always table-reading in disguise: a two-way frequency table splits people by two characteristics, and you compute the probability of one characteristic — often given the other (conditional probability). Pure formula-based probability is rare.
The whole skill reduces to choosing the right denominator. "What fraction of left-handed students are seniors" restricts the world to left-handed students — that row or column total is your denominator, not the grand total. Underline the 'given' group in the question, find its total in the table, then count the overlap.
Straight from the Grind1600 question bank — try each one before revealing the answer.
Correct answer: A
Choice A is correct. The total number of possible outcomes for rolling a fair 8-sided die is 8. The number of possible outcomes for rolling a 5 is 1. The probability is 1/8. Choice B is the probability of rolling 5 or less. Choice C is the probability of rolling greater than 5. Choice D is the probability of rolling a number other than 5.
Correct answer: 9
The correct answer is 9. P(red) = 3/8, so there are (3/8)(24) = 9 red marbles. P(blue) = 1/4 = 2/8, so there are (1/4)(24) = 6 blue marbles. The remaining marbles are green: 24 - 9 - 6 = 9 green marbles.
Ratios, Rates & Units
Setting up proportions, converting units, and reasoning with rates — the most common word-problem machinery on the SAT Math section.
Percentages
Percent change, percent of a quantity, reverse-percentage problems, and multi-step percent scenarios like tax-plus-discount.
Data Distributions & Measures of Center
Mean, median, mode, range, and standard deviation — and how outliers or skew change them — read from lists, tables, and frequency plots.
Scatterplots & Two-Variable Data
Reading scatterplots, lines of best fit, interpreting slope in context, and distinguishing linear from exponential association.
Inference & Margin of Error
What sample results let you conclude about a population, how margin of error works, and why sample size changes confidence.
Evaluating Statistical Claims
Judging what a study design supports: random sampling vs. random assignment, causation vs. correlation, and generalizability.
