Algebra 1

Independent events. There are two probabilities,p(blue 1 or 2) and P(green 1): P(blue 1 or 2)=$\frac{1}{6}$+$\frac{1}{6}$=$\frac{2}{6}$ =$\frac{1}{3}$ P(green 1)=$\frac{1}{6}$ P(blue 1 or 2 and green 1)=P(blue 1 or 2) $\times$ P(green 1) P(blue 1 or 2 and green 1)=$\frac{1}{3}$ $\times$ $\frac{1}{6}$ P(blue 1 or 2 and green 1)=$\frac{1}{18}$
