Ateacher designed a probability simulation using a coin to model the answers of students who guess every answer on a 5-question true- false quiz. in this simulation, a coin is tossed 50 times, and its landing position is recorded. a coin that lands on heads is recorded as a correct answer, while a coin that lands on tail is recorded as an incorrect answer. the results are shown below.

which conclusion can be inferred from these results?

the initial coin toss was marked correct 7 times, so a student is likely to get correct answers by guessing.

there was a total of 26 coin tosses that were marked incorrect, so a student will never pass by guessing.

there was no trial in which all 50 coin tosses were marked correct, so a student is more likely to get all incorrect answers by guessing.

there were approximately an equal number of heads and tails in each trial, so the average grade of all students who guess at every item will be about 50%.
