P(blue) = total number of blue

so do i divide each number by the total number of boxes?

anonymous · Answer

115/450 then 190/450, 145/450

campbell_st · Answer

no, you just want the porbability of a blue toy.. 

$$P(blue) = \frac{number~ of ~blue~toys}{total ~number ~ of ~boxes}$$

P(blue) = 28/90

but otherwise you're corrrect
