The probability that a seventh-grade student will win the raffle is 3/8.
What is probability?
"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".
For the given situation,
Number of students in sixth grade = 80
Number of students in seventh grade = 90
Number of students in eighth grade = 70
Total number of students in school = 240
The event is the the probability that a seventh-grade student will win the raffle
Thus, the probability that a seventh-grade student will win the raffle[tex]P(e)=\frac{90}{120}[/tex]
⇒[tex]P(e)=\frac{3}{8}[/tex]
Hence we can conclude that the probability that a seventh-grade student will win the raffle is 3/8.
