Professor Wright allow students in her Business Writing class an opportunity to complete up to 3 bonus assignments. It is up to students to decide how many of the bonus opportunities they will complete. The probability distribution for the number of bonus assignments completed by students is given in the table, where x is a random variable that represents the number of assignments completed by a randomly- selected student. X 0 P(x) 0.45 1 2 3 0.25 0.2 0.1 a. Compute the expected value of the distribution. Expected value = b. What is the probability that a randomly selected student completes fewer than 2 bonus assignments?
