The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.
<h3>How to calculate the probability?</h3>
In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.
- Let S represent studied for.
- Let B represent a score of B or higher grade
Therefore, we need to find P(S|B):
S|B = 0.80.

<u>Complete Question:</u>
At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
The cost of ending inventory at the conclusion of an accounting period is calculated using the weighted average inventory costing method.

How is the cost of discontinuing inventory calculated?</h3>
- The cost of ending inventory at the conclusion of an accounting period is calculated using the weighted average inventory costing method. The idea behind this approach is to give all inventory units an average cost.
- In this scenario, the average of the purchase costs from April 5 to April 22 would be taken and multiplied by the number of remaining units to get the cost of the ending inventory on the balance sheet.
- The five pieces cost a total of $69 ($10 + $12 + $14 + $16 + $17) between April 5 and April 22. The remaining four units would make up the ending inventory as one unit was sold on April 25.
- Therefore, $17.25 ($69 divided by 4) would be the price of the closing inventory. As the cost of the ending inventory, this sum would be shown on the balance sheet.
