Math. Probability help. Fan and medal.

Answer 1

All of the students in the Physics Club want to attend a trip to an amusement park. There are 18 students in the club but only 9 tickets available for the park. A random number will be generated to select the 9 students who will attend the trip.

The teacher asks each student to write down a different number from 1 to 18, and then a random number is generated. The 9 students whose numbers match or are closest to the number generated will attend the trip.

Which is a true and correctly justified statement about whether the way the students are selected for the trip is fair?

The way the students are selected is unfair because more than one student cannot write down the same number.

The way the students are selected is fair because each student has an equal chance of writing down the number that is generated.

The way the students are selected is fair because the range of numbers generated is the same as the number of students in the club.

The way the students are selected is unfair because students are not allowed to discuss the numbers they have chosen before the random number is generated.
