First, notice that we have in total 15 items. Then, we have that the probabilities are:
[tex]\begin{gathered} \text{ \# of items with yellow: }3 \\ \Rightarrow P(Yellow)=\frac{3}{15}=\frac{1}{5} \\ \text{ \# of items with purple: 2} \\ \Rightarrow P(Purple)=\frac{2}{15} \\ \text{ \# of items striped: 4} \\ \Rightarrow P(not\text{ striped)}=1-P(striped)=1-\frac{4}{15}=\frac{11}{15} \\ \text{ \# of items solid: 5} \\ \Rightarrow P(solid)=\frac{5}{15}=\frac{1}{3} \\ \text{ \#items with polka dot: 3} \\ \Rightarrow P(not\text{ polka dot) = 1 - P(polka dot) = 1-}\frac{3}{15}=\frac{4}{5} \end{gathered}[/tex]
