[tex]\begin{gathered} \text{Total}=8+2+5+7 \\ \text{Total}=22 \\ \text{White marble} \\ P=\frac{5}{22} \\ \text{The probability of selecting a white marble is }\frac{5}{22} \\ \text{red marble} \\ P=\frac{8}{22}=\frac{4}{11} \\ \text{The probability of selecting a red marble is }\frac{4}{11} \\ \text{black marble} \\ P=\frac{7}{22} \\ \text{The probability of selecting a black marble is }\frac{7}{22} \\ \text{Green marble} \\ P=\frac{0}{22}=0 \\ \text{The probability of selecting a gre}en\text{ marble is }0 \\ \text{red , white or blue marble} \\ P=\frac{4}{11}+\frac{5}{22}+\frac{2}{22} \\ P=\frac{15}{22} \\ \text{The probability of selecting a red , white or blue marble marble is }\frac{15}{22} \end{gathered}[/tex]
