Please help with this question, thanks!

3. Let P(e) be the probability of an event e, and let n be an integer. The probabilities of n having certain values are shown below. P(n =0) = 0.0125 P(n = 1) 0.225 P(n=2) 0.0125 P(n = 3) = 0.5 P(n=4) 0.0125 P(n = 5) = 0.225 P(n = 6) 0.0125 = 3a. (10 points.) Suppose we want to search an OBST to see if it has a key n. Using these probabilities, construct an OBST in which search succeeds when ne { 1,3,5 }, but fails otherwise
