Question

Faculty positions in a school district are classified as either teacher or administrator based on primary duties and responsibilities. The table below shows information on the number of national board-certified and not board-certified teachers and administrators.

What is the probability that a randomly chosen faculty member is either board-certified or a teacher? Please enter your answer as a percent rounded to two decimal places.

Explanation / Answer

P(Board Certified or Teacher) = (22+10+14)/(22+10+14+11)

P(Board Certified or Teacher) = 46/57

P(Board Certified or Teacher) = 80.70%

So, answer is 80.70%
