Using Cross Products to Solve Probability Equations
Using Cross Products to Solve Probability Equations is a skill on Pengi from Section 15.3: Experimental and Theoretical Probability in Big Ideas Math, Advanced 2.
Key Concepts
When solving probability equations with unknown values, use cross products: if $\frac{a}{b} = \frac{c}{d}$, then $a \cdot d = b \cdot c$.
For probability problems: $\frac{\text{favorable outcomes}}{\text{total outcomes}} = \frac{\text{expected successes}}{\text{total trials}}$.
