Question involving the selection of two apples from a bag of red and yellow apples without replacement. Assume that the bag has a total of 18 apples: 8 red and 10 yellow.
(1) What is the probability that the second apple you pick is red?
(2) What is the probability that you pick at least one red apple?

Best ResponseYou've already chosen the best response.2a) The probability that the first apple you pick is red = 8/18 The probability that the second apple you pick is also red = 7/17 Tot Probability= 56/306  The probability that the first apple you pick is yellow = 10/18 The probability that the second apple you pick is red = 8/17 Tot Probability = 80/306  Added together = 136/306 = 4/9  b) calculate the probability that you don't pick any red apples. = 10/18 * 9/17 = 90/306 = 5/17 1 5/17 =12/17

Best ResponseYou've already chosen the best response.0Jadedry answers are right. dw:1443697090611:dw . Alternatively, you can use probability tree to solve the problem.

Best ResponseYou've already chosen the best response.2@Pulsified333 No problem, happy to help! Remember that if events are dependent on each other, you have to multiply. If they are not, you can add them up.
