So to solve this let's find the probability of the first scenario then add the second scenario: 4/11 * 7/10 + 7/11 * 4/10= 50.9%. Now we want both balls to be red so let's find the probability of that happening: 5/17*4/16= 7.35%. Upvote • 0 ...

WebbThe process of not replacing the first drawn object or an item to its sample description space before selecting the second object or an item is termed probability without replacement. In other words, it is defined as an object or an item that cannot be selected or drawn more than once. WebbThe probability of choosing the blue ball is 2/10 and the probability of choosing the green ball is 3/9 because after the first ball is taken out, there are 9 balls remaining. So the probability is: 2/10 x 3/9 = 6/90 or 1/15 = 6.7% (Compare that with replacement of 6/100 or 6%) What does probability without replacement mean? Sampling without ...

WebbThe draws in probability with replacement are independent events.
