An archer can either hit or miss his target. The probability of hitting a target is 70.0% . Suppose, he will take 19 attempts on a specific day. a. What is the mean number of attempts in which he hits the targets? Answer in exact fraction, or rounded to at least 2 decimal places. b. What is the standard deviation in the number of successful attempts? Answer in exact fraction, or rounded to at least 2 decimal places. c. What is the probability that the number of successful attempts is more than 1 standard deviations away from the mean value? Answer in exact fraction, or rounded to at least 4 decimal places.
