Answer:
To find the probability that the student chosen at random was male OR received a grade of "C," we need to calculate the probability of each event separately and then add them together.
Probability of being male = (Number of male students) / (Total number of students) = (30) / (68) ≈ 0.4412
Probability of receiving a grade of "C" = (Number of students who received a grade of "C") / (Total number of students) = (23) / (68) ≈ 0.3382
To find the probability of the student being male OR receiving a grade of "C," we add the individual probabilities:
Probability of being male OR receiving a grade of "C" = Probability of being male + Probability of receiving a grade of "C" - Probability of being male AND receiving a grade of "C"
Probability of being male OR receiving a grade of "C" = 0.4412 + 0.3382 - (7/68) ≈ 0.7794
Therefore, the probability that the student chosen at random was male OR received a grade of "C" is approximately 0.7794.
