Wendy wanted to understand whether students at her school were in favor of an extended school day. She surveyed some students an
d displayed the results in the table below: In favor Opposed Undecided
Grade 9 4 7 7
Grade 10 9 11 5
Grade 11 12 13 5
Grade 12 10 5 12
If the principal randomly selects a student in grade 12 from this survey, what is the probability that the student is in favor of extending the school day?
If the principal randomly selects a student in grade 12 so this means we focus on just the "grade 12" row. No other rows will be looked at here<span> what is the probability that the student is in favor of extending the school day?"</span> find the number in favor (who also happen to be in grade 12) then divide that number by the total number in grade 12 make sense.
