how do I solve these 3 questions

Suppose A is a random variable with mean . What can you say about P(X > 3p)? Suppose in addition, that X has variance o'. What can you say about P(u - 30 Xx. Approximate P(X > 18) using the Cen- k=1 tral Limit Theorem. Leave your answer in terms of @(z), the cumulative distribution function for the standard normal random variable
