------------- Solutions 

Part 1: [tex]Science - Art - Math = Answer[/tex] 

[tex]Science = \frac{1}{3} [/tex] 

[tex]Art = \frac{1}{2} [/tex] 

[tex]Math = \frac{1}{1} [/tex] 

[tex] \frac{1}{3} * \frac{1}{2} * \frac{1}{1} = \frac{1}{6} [/tex] 

[tex] \frac{1}{3} * \frac{1}{2} * \frac{1}{1} = \frac{1}{6} [/tex]  

[tex]P(A) = \frac{1}{6} + \frac{1}{6} = \frac{2}{6} [/tex] 

Part 2: [tex]Blue - Head = Answer[/tex] 

[tex]Blue = \frac{1}{4} [/tex] 

[tex]Head = \frac{1}{2} [/tex] 

[tex] \frac{1}{4} * \frac{1}{2} [/tex] 

[tex] = 1 * 1 = 1 4 * 2 = 8 [/tex] 

[tex] \frac{1}{4} * \frac{1}{2} = \frac{1}{8} [/tex] 

Part 3: [tex]Red + Pink [/tex] 

Part 4: Card Color    Green                 Yellow                  Purple 
                 Purple Green,    Purple Yellow,      Purple Purple,    Purple 
                Green Green,      Green Yellow,      Green Purple,    Green
