Inclusive Events
Calculate Inclusive Events in Grade 10 math: apply counting principles and probability formulas to solve real-world problems with Saxon Algebra 2 Saxon Algebra 2.
Key Concepts
For two inclusive events A and B: $$P(A \text{ or } B) = P(A) + P(B) P(A \text{ and } B)$$.
A standard die is rolled. Find the probability of rolling an even number or a number greater than 3. $$P(\text{even or 3}) = P(\text{even}) + P( 3) P(\text{even and 3}) = \frac{3}{6} + \frac{3}{6} \frac{2}{6} = \frac{4}{6} = \frac{2}{3}$$ A card is drawn from a standard 52 card deck. Find the probability of drawing a face card or a spade. $$P(\text{face or spade}) = \frac{12}{52} + \frac{13}{52} \frac{3}{52} = \frac{22}{52} = \frac{11}{26}$$.
Imagine you're picking a card. What's the chance it's a heart OR a king? You add the probabilities, but wait! The King of Hearts got counted twice. We must subtract that overlap to be accurate. This formula is your tool to fix that double counting problem when events share outcomes and can happen at the same time.
