3. Let the amount of rain on rainy days be normally distributed with a mean of 3 cm and standard deviation of 1cm. (a) Find the probability that there is at least 2cm of rain on a randomly chosen rainy day. You can use a normal table to get the probabilities needed or use pnorm() in R. Do get a final answer that is numerical and not just a function of Φ(), the standard normal cdf. (b) Suppose on rainy...
