Last semester, a certain professor gave 43 As out of 242 grades. If one of the professor's students from last semester were selected randomly, what is the probability that student received an A? (Assume that each student receives one grade.)

43/242 = ?

0.18 To find the probability that a randomly selected student received an A, we need to divide the number of students who received an A by the total number of students.

First, we know that the professor gave 43 As out of 242 grades. This means that 43 students received an A.

To find the total number of students, we use the fact that each student receives one grade. Therefore, the total number of students is equal to the total number of grades, which is 242.

Now, we can calculate the probability by dividing the number of students who received an A by the total number of students:

Probability of receiving an A = Number of students who received an A / Total number of students
= 43 / 242
≈ 0.178 (rounded to three decimal places)

Therefore, the probability that a randomly selected student received an A is approximately 0.178.
