A recent study found that highly experienced teachers may be associated with higher student achievement. Suppose fourth-grade students at an elementary school are randomly assigned to one of eight teachers. Teachers Nagle, Crouse, Warren, Tejada, and Tran are considered highly experienced. Teachers Cochran, Perry, and Rivas are considered less experienced.
a. List the equally likely outcomes that could occur when a student is assigned to a teacher.
b. What is the probability that a fourth-grade student at this school is assigned to a highly experienced teacher?
c. What event is the complement of the event described in part (b)? What it the probability of this event?
