Answer:
0
Step-by-step explanation:
it is zero because in the question it says there are 20 "bad" oranges so even the possibility of finding one good one is 0. so for a), b) and c) are all 0 possibility.
It that's not the required answer in options. Then please review the question. If there was any specification on the total number of oranges. Then subtract 3 from it, that is your denominator. For numerator subtract 17 from it. Then you will get the answer for at least one good orange. so dividing it by 2 you will get answer for a).
