Interphase is the period between mitotic events; all other phases are part of mitosis and their individual probabilities add up to the total probability of seeing cells undergoing mitosis. Pay attention to the individual probabilities for cells in each phase of the cell cycle. Problem N° 10 For a certain type of animal tissue, the probability of a randomly selected cell being in a particular stage of the interphase/mitosis cycle is given by the following table: Stage Probability Interphase 0.5 Prophase 0.1 Metaphase 0.05 Anaphase 0.2 Telophase 0.15 Suppose you examine 100 cells at random from this tissue.
