Question

Mark, Anthony, and Derek, are going on a road trip and will take turns driving the car. They need to decide who will drive first.

Which method assures that each of the three friends has a fair chance of being selected to drive first?
O A. "Using a random number generator, generate an integer. If the number is negative, Mark drives first. If the number is positive,
Anthony drives first. If the number is 0, Derek drives first.
OB.
Flip two fair coins. If both coins land on tails, Mark drives first. If both coins land on heads, Anthony drives first. If one coin
lands on tails and the other lands on heads, Derek drives first.
O C. Spin a spinner with four equal-sized sections labeled A, B, C, and D. If the spinner lands on A, Mark drives first. If the spinner
lands on B, Anthony drives first. If the spinner lands on C, Derek drives first. If the spinner lands on D, Mark drives first.
OD. Roll an ordinary die. If the die lands on 1 or 4, Mark drives first. If the die lands on 2 or 5, Anthony drives first. If the die lands
on 3 or 6, Derek drives first.

Answer 1

Option D: Roll an ordinary die. If the die lands on 1 or 4, Mark drives first. If the die lands on 2 or 5, Anthony drives first. If the die lands on 3 or 6, Derek drives first.

Step-by-step explanation:

The method that assures that each of the three friends has a fair chance of being selected to drive first is Option D: Roll an ordinary die. If the die lands on 1 or 4, Mark drives first. If the die lands on 2 or 5, Anthony drives first. If the die lands on 3 or 6, Derek drives first.

Using a fair die ensures that each of the three friends has an equal probability of driving first. Since a fair die has six sides and each side has an equal chance of landing face up, there is a 1/6 probability that the die will land on any specific number. Therefore, each friend has a 1/6 chance of being selected to drive first.
