There are 9 red gumballs, 5 green gumballs, 8 yellow gumballs, and 8 blue gumballs, what is the probability of choosing green then yellow. please explain how you got your answer.
The probability of choosing green ball is [tex]\dfrac{5}{30}=\dfrac{1}{6}[/tex] The probability of choosing yellow ball is [tex]\dfrac{8}{30}=\dfrac{4}{15}[/tex]
So, the probability of choosing green ball and then yellow one is [tex]\dfrac{1}{6}\cdot\dfrac{4}{15}=\dfrac{2}{45}[/tex]
