Maria and ralph are peeling apples. the time it takes maria to peel an apple is approximately normally distributed with mean 12 seconds and standard deviation 2 seconds. the time it takes ralph to peel an apple is approximately normally distributed with mean 11 seconds and standard deviation 2.5 seconds. 1. find the probability that (starting together) maria finishes her next apple before ralph. 2. if the first person done always waits for the second person to finish (so that they always start together), ralph will finish first ‪ percent of the time.
