Samples of rejuvenated mitochondria are mutated (defective) in 1% of cases. Suppose 14 samples are studied, and they can be considered to be independent for mutation. Determine the following probabilities. (a) No samples are mutated. (b) At most one sample is mutated. (c) More than half the samples are mutated.
