Answer:

19/37

Explanation:

The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor

Total number of people in the faculty =

9 professors + 8 associate professors+ 10 assistant professors+ 10 instructors

= 37 people

Hence,

The probability of choosing a professor or an instructor

= P( Professor) + P( Instructor)

= 9/37 + 10/37

= 19/37
