Question 1057997: a bag contains 15 red and 10 green marbles. a marble is drawn, replaced in the bag, then a second marble is drawn. are the events "first marble is red" and "second marble is green" independent events

Yes, the events are independent because the probability of the outcome of the second event is not affected by the outcome of the first event.

This is because the first marble is replaced in the bag. If the first marble was not replaced, then the events would not be independent.
