In a class of students, the following data table summarizes
how many students passed a test and complete the homework
due the day of the test. What is the probability that a student
chosen randomly from the class did not complete the
homework?
Passed the test Failed the test
Completed the homework
Did not complete the homework
4

Step-by-step explanation:

you have t as a total amount of the whole class.

f= did not pass and you place the total number next to it like this;  f/t represents that group. You continue this in your workings.

f/t = probability failed.

p/t = probability passed

c/t = probability completed

dc/t = probability did not complete

and draw a tree.

The random would be either of these, we know there s a possibility of 1/4 but the odds stay central. We look for a new way after this data is converted as a  fraction and show these fractions as your answer.
