Consider 3 trials, each having the same proba- bility of success. let x denote the total num- ber of successes in these trials. if e[x] = 1.8, what is (a) the largest possible value of p{x = 3}? (b) the smallest possible value of p{x = 3}? in both cases, construct a probability scenario that results in p{x = 3} having the stated value. hint: for part (b), you might start by letting u be a uniform random variable on (0, 1) and then defin- ing the trials in terms of the value of u.
