QuestionThe math department at your school is giving away a graphing calculator as a prize to celebrate math month. There are 800 students at the school. There are 240 freshmen, 207 sophomores and the remaining students are juniors and seniors.
If a student is chosen at random, what is the probablity that the student is not a freshmen?

Studdy Solution
Calculate the probability that a randomly chosen student is not a freshman. This is the number of students who are not freshmen divided by the total number of students:
$\frac{560}{800}$
Simplify the fraction:
$\frac{560 \div 80}{800 \div 80} = \frac{7}{10}$
The probability that a student chosen at random is not a freshman is:
$\boxed{\frac{7}{10}}$
