In a country, a day can be either rainy or sunny. The probability of a day being rainy is 50.0% . Suppose, you have chosen 17 random days in a year. a. What is the mean number of rainy days among all those chosen days? Answer in exact fraction, or rounded to at least 2 decimal places. b. What is the standard deviation in the number of rainy days? Answer in exact fraction, or rounded to at least 2 decimal places. c. What is the probability that the number of rainy days is more than 2 standard deviations away from the mean value? Answer in exact fraction, or rounded to at least 4 decimal places.
