Please help me answer both these questions since they are both related. Probability is a tough topic for me. Thank you!

3) Consider randomly sampling from a theoretical normal distribution (and remember symmetry implications). a. [1 pt] What is the probability that observations from a sample size of n=2 will both have values above the mean? b. [1 pt.] What is the probability that observation from a sample size of n=4 will all have values above the mean? c. [1 pt] What is the probability that observations from a sample size of n=8 will all have values above the mean? 4) [1 [It] How do the answers to question 3 provide insight into the fact that the standard error of a sampling distribution decreases with sample size
