Answer 2

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$P(e)=\frac{90}{120}$

⇒$P(e)=\frac{3}{8}$

Hence we can conclude that the probability that a seventh-grade student will win the raffle is 3/8.
