PLEASE HELP ! WILL MARK BRAINLIEST !You have seven red marbles and seven blue marbles in a bag. You randomly take a marble from the bag , and then you randomly take another marble from the bag without returning the first marble to the bag. What is the probability that both marbles are red?
In the first round of picking a marble, the chance of getting red is 7 out of 14 [7/14]. In the second round, since you took a red marble before, taking red the second time will be 6 out of 13 marbles [6/13]. So we multiply the chances of red the first time by the chances of red the second time [ 7/14 * 6/13 ] and we get our answer that the chance of picking red both times... is 3/13.
Hope you learn how to math from this! [and save you]
