anonymous · Answer

i guess from the data we are supposed to conclude that since out of 30 draws she got a green on 6 times then the probability of getting a green one is $\frac{6}{30}=\frac{1}{5}$ and similarly the probability of getting a purple one is $\frac{4}{30}=\frac{2}{15}$
multiply these two numbers together to get your answer

anonymous · Answer

4/30 X 2/15 = 4/225 ?

anonymous · Answer

6/30 X 1/5 = 1/25 ?

anonymous · Answer

$$\frac{1}{5}\times \frac{2}{15}=\frac{2}{75}$$
