Hi there!
We are given the coordinates (26, 56) and (26, 1)
We want to find the midpoint of these two points
The midpoint can be found using the formula , where
&
are points
We have 2 points, which is what we need to find the midpoint, but let's label the values of the points to avoid confusion and mistakes when actually calculating
Now substitute these values into the formula.
Add the numbers together

Answer:
There is a 52% probability that she will get it right.
Step-by-step explanation:
We have these following probabilities:
A 40% probability that the student knows the answer to a question.
A 60% probability that the student does not know the answer to a question.
If the student does not know the answer to a question, a 20% probability of getting the question right guessing.
If we choose a question at random from the exam, what is the probability that she will get it right?
40% probability that she knows the answer
60% that she has to guess, when there is a 20% probability of getting it right. So
There is a 52% probability that she will get it right.
