As these cells are non-photosynthetic, all other organelles would be found in these cells except for chloroplasts which contain photosynthetic pigments used for photosynthesis. A few examples of structures found within these cells would be cell wall, cell membrane, cytoplasm, ribosomes, nucleoloid and many others. Do note that prokaryotic cells do not have organelles with membranes hence they do not have mitochondria or lysosomes or endoplasmic reticulum etc.
I think there is a 50% chance of the coin landing on either side because the labelling of the coin will not affect the balance of the coin, and therefore won’t alter the flip. Labelling the coin ‘b’ and B’ will result in a coin flip no different from if the coin remained unlabelled.
