4. The heights of fully grown oak trees in a certain co 90 feet and a standard deviation o=3.5 feet. If you were to take a large number of randon grown oak trees in a certain county are normally distributed with a mean ake a large number of random samples of size n = 4 trees, find the following 3. If S = {0,1,2,3,4,5,6,7,8,9) A = {0,1,3,7,8). B={0,2,3,5,6,7}, and C={3,4,7,8}, (a) list the outcomes in the sets. Set braces required. (1) B'nc (ii) AUC (b) find the probability of each event. Give answer as a fraction in lowest terms. (1) P(AB) (ii) P(BUC) In how many distinguishable ways can the letters of the word STATISTICS be arranged?
