“Suppose you have a bag containing 5 red marbles, 3 blue marbles, and 2 green marbles. You randomly select two marbles from the bag without replacement. What is the probability that the first marble drawn is red and the second marble drawn is blue?”
Absolutely! Let’s analyze the scenario to find the probability of drawing a red marble followed by a blue marble without replacing them.
We can approach this problem by considering the probability of each event happening sequentially.
Probability of drawing a red marble first:
Probability of drawing a blue marble second (after taking out a red marble):
Now, to get the overall probability of both events happening (red first, then blue), we multiply these two probabilities:
(Probability of red) * (Probability of blue after red) = (5/10) * (3/9)
This simplifies to 1/6.
Therefore, the probability of drawing a red marble followed by a blue marble without replacement is 1/6.
