It depends on whether or not you can see and/or feel the fruit when you select a piece. Most of us with normal vision can determine the difference between apples, oranges, and bananas, hence the probability of selecting a banana from among the other listed fruits is near certainty regardless of the numbers of pieces of each sort of fruit - if we can see all of the fruit when we pick. Likewise, if we are asked to reach into a bag, most of us would be able to tell by feel whether we had a spherical object (not a banana) or a curved cylindrical object (a banana) in our hand. Hence the probability is again near certainty that a banana would be chosen if the successful outcome of the experiment were defined as selecting a banana rather than an orange or an apple.
On the other hand, if the experiment involved shaking an opaque bag containing 6 oranges, 8 apples, and 4 bananas, such that one piece of fruit emerged a a time and presuming that the likelihood of the appearance of each type of fruit was equal, then yes, there are 18 possibilities of which 4 are successes, so the probability that the first piece of fruit to emerge from the bag is a banana is:
