3. A school system compiled the following information from a survey it sent to people who were juniors 10 years earlier. 3 -1 Lines and Angles Holt Geometry

3 -1 Lines and Angles • 85% of the students graduated from high school. • Of the students who graduated from HS, 90% are happy with their present jobs. • Of the students who did not graduate from HS, 60% are happy with their present jobs. Holt Geometry

Lines and Angles 3 -1 What is the probability that a member of the junior class 10 yrs. ago graduated from high school and is happy with his or her present job? Make a tree diagram to organize the information. Holt Geometry
