Question 7:

[Calculator Allowed] The incomplete table shown summarizes the number of students with their junior license and senior license for 17 and 18 year olds at Lincoln High School. There are 3 times as many 17 year olds with senior licenses as there are 17 year olds with junior licenses, and there are 14 times as many 18 year olds with a senior license as there are 18 year olds with a junior license. Based on the table shown, which of the following is the number of students at Lincoln High with either a junior or senior license, given that they are 18 years old?

Question 8:

[Calculator Allowed] The incomplete table shown summarizes the number of students with their junior license and senior license for 17 and 18 year olds at Lincoln High School. There are 3 times as many 17 year olds with senior licenses as there are 17 year olds with junior licenses, and there are 14 times as many 18 year olds with a senior license as there are 18 year olds with a junior license. Based on the table shown, which of the following is closest to the probability that a student with a junior license selected at random is 17 years old?
