Question

Carla is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability that Carla will get a green or yellow marble on the first draw and a blue on the second draw?
(3 green, 4 yellow, 5 blue, 8 pink)

Answer 1

\[\frac{7}{20}\times \frac{5}{20}\]

Answer 2

green 3/20 yellow 1/5 blue 5/19

Answer 3

probability of getting green OR yellow is
\[\frac{7}{20}\] and the probability of getting blue is
\[\frac{5}{20}=\frac{1}{4}\] and you want BOTH so multiply

Answer 4

i get
\[\frac{7}{80}\]

Answer 5

you are finding the probability of getting blue on the second draw where one has already been taken out making the total 19.

Answer 6

the probability of getting a blue on the first draw is in fact 1/4 but on the second draw it is 5/19
