Give the probability in decimal form (correct to two decimal places). A calculator may be helpful.
Last semester, a certain professor gave 35 As out of 259 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.)
Looks like that professor is still giving those A's

To calculate the probability, we need to divide the number of favorable outcomes (the number of students who received an A) by the total number of possible outcomes (the total number of students graded).
The given information tells us that out of 259 grades, 35 were A's. So, the probability of a student from last semester receiving an A can be calculated as follows:
Probability = Number of A's / Total number of grades
Probability = 35 / 259
To get the answer in decimal form, we can use a calculator to divide 35 by 259.
The calculated probability is approximately 0.14, when rounded to two decimal places.
Therefore, the probability that a student from last semester received an A is approximately 0.14 or 14%.
