Last semester, a certain professor gave 11 As out of 226 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.)
well, how about 11/226 ?
You invest $1,300 in an account with an annual interest rate of 2.5%, compounded monthly. How much money is in the account after 10 years? Round your answer to the nearest whole number.
To find the probability that a student received an A, first, we need to determine the total number of grades that were given out. In this case, the professor gave out 226 grades.
Next, we need to determine the number of As given out by the professor. According to the question, the professor gave 11 As.
Now, we can calculate the probability using the formula:
Probability = Number of favorable outcomes / Total number of possible outcomes
In this case, the favorable outcome is receiving an A, and the total possible outcome is any grade given out by the professor.
So, the probability of a student receiving an A can be calculated as:
Probability = Number of As / Total number of grades
= 11 / 226
Therefore, the probability that a student received an A is approximately 0.0487 or 4.87%.
