In a school, 22% of the students are sixth graders. What is the probability that a randomly chosen student will not be a sixth grader? 26 points

Respuesta :

Probability = Favorable Outcome / Total Outcome
P = 100 - 22 / 100
P = 78 / 100
P = 0.78

In short, Your Answer would be 0.78 or 78%

Hope this helps!
Since 22% of the school are sixth graders, 78% are not. Therefore, the probability that a randomly chosen student will not be a sixth grader would be 78%. Hope this helps :)
