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.

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour.valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house.which graph correctly represents valerie's distance from her house after her coffee break?
