Well here im going to give you the process so that you can figure it out: The probability that Jonas will get an orange is 5/13.We know this because if Jonas gets an orange there are now 12 pieces of fruit remaining. Therefore the probability that Beth will get an apple is 5/12. What you need to do is to multiply these two values of probability to find the required probability. Hope this has helped
