Answer:

Choice C; The flight will be late on one of the three days.

Step-by-step explanation:

The flight is 75% of the time. This means that out of 4 flights, 3 are on time and the result of Franc's spinner should reflect this fact, i.e his spinner should give 75% probability of flights on time.

Choice A says the flight is on time 0% of the time, This is not true, therefore this is not a correct interpretation of the three spins.

Choice B says the flight is on time 100% of the time, This is not true, therefore this is not a correct interpretation of the three spins.

Choice C says the flight is on time 66% of the time, which is close to 75%. Therefore this choice is close and correct.

Choice D says the flight is on time 30% of the time, This is not true, therefore this is not a correct interpretation of the three spins.

Thus only choice C is correct.
