Based on the probabilities given, the student will study for B. Science, because the probability of getting all questions correct is 0.008, which is lower than for history (0.063).
<h3>Which subject will the student study?</h3>
Out of the subjects the student has to take, the subject that have the lowest probability of passing is Science at 0.008.
This is the subject that they would most likely study because they have the highest chance of failing if they guess.
The reason why c = 6n + t is the same as c - t = 6n is because c is the sum of the addition problem. 6n and t are the addends. The inverse operation for addition is subtraction. c is the cost that will be reduced by t. The answer is still 6n.
