I've attempted to answer this and missed it entirely. I entered the mean and standard deviation as decimals of .11 and .02, that was wrong, based on that everything else was off, I also have no idea how to find the 71th? Percentile. I'm so lost

The average THC content of marijuana sold on the street is 11%. Suppose the THC content is normally distributed with standard deviation of 2%. Let X be the THC content for a randomly selected bag of marijuana that is sold on the street. Round all answers to 4 decimal places where possible, a. What is the distribution of X? X ~ N( b. Find the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 9.6. c. Find the 71th percentile for this distribution
