Learning standards covered
OGM.9.SP.5Open Global Math Standards 2026™ · 8th GradeCalculate theoretical and experimental probabilities for simple and compound events using tree diagrams, Venn diagrams, two-way tables, and counting principles; apply the complement rule (P(A') = 1 - P(A)) and use simulations / law of large numbers to estimate probabilities.
OGM.9.SP.4Open Global Math Standards 2026™ · 8th GradeConstruct and interpret two-way frequency and relative frequency tables for bivariate categorical data; assess patterns of association using row and column conditional relative frequencies.
