A bag contains three red marbles and eight blue marbles. Your randomly pick a marbles and then pick a second marble without returning the marbles to the bag. What is the probability that the first marble is red and the second marble is blue?
help me please
Im not sure about this but
Probability of picking a first red marble is 3/11 since there are 3 red marbles in a total of 11 marbles.
Probability of picking a second red (without replacement) is 2/10 (or 1/5) since there are 2 red marbles left in a total of 10 marbles left
Probability of the 2 events happening in succession is (3/11 * 2/10) * 100 = 5.5%
