Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375.What is the probability that both are red?
In conclusion, the probability that both of the balls are red is 1/10.- The probability of the first marble being red is 943. After returning this marble to the bag, the probability of the second marble being blue is 1143. So the probability picking a red marble, and then a blue marble is 943?1143?0.054.
