If an organism is treated with a dose of radiation that quadruples the rate of mutation observed in the absence of radiation and a mutation subsequently occurs, what is the probability that it was caused by the chemical agent?

The question tells us that radiation quadruples the rate of mutation, which means that if the probability of mutation in absence of radiation is x, the probability of mutation with radiation is 4x. Therefore, the probability that the mutation was caused by the chemical agent is 3/4 (1 - 1/4).
