Question

asking every 3rd student to walk in the building what their favorite breakfast is
asking people standing in line to buy a ps5 whether they prefer xbox or playstate
asking the band students at a school if more money should be spent on athletics
asking people attending a football game what their favorite sport is
which of the following is a random sample?

Explanation:

A random sample is a subset of a population selected in a way that each member of the population has an equal chance of being included. In the first option, only 3rd - grade students are asked. In the second option, only people in a specific line (to buy a PS5) are asked. In the third option, only band students are asked. In the fourth option, people attending a football game (a more diverse group compared to the first three non - random samples) are asked, and assuming the football - game attendees are a more representative cross - section (if the sampling is done properly among them), this has a higher chance of being a random sample.

Answer:

Asking people attending a football game what their favorite sport is.
