Question:

In studies of anticancer drugs it was found that if if mice are injected with cancer cells, the survival time can be modeled with the exponential distribution. Without treatment the expected survival time was 10 h. What is the probability that

b. The survival time of a mouse exceeds the mean value by more than 2 standard deviations? More than 3 standard deviations?
