Question

Redmond Elementary School has 3rd, 4th, and 5th grade classes. First, a class will be randomly selected and we will record if it is a class of 3rd, 4th, or 5th graders. Then, a student within the class will be selected at random and we will record if the student is a boy or girl. For example, one possible outcome in the Sample Space is 4G (4th grade class is selected, then a girl).

8a Draw a tree diagram, then write out the Sample Space using set notation.

8b Write the following events in set notation. For example: the event a third grader is selected = { 3B, 3G }.

A = the selected student is a girl

B = the selected student is a 3rd grader or a boy

C = the selected student is not in 4th grade
