Question

PLEASSE HELP URGENT WILL GIVE BRAINLIEST FOR CORRECT ANSWER Brian wanted to find out if studying for the algebra test is effective. He surveyed some learners in his class. These are the results.
64 learners studied for the test and passed.
4 learners passed the test without studying.
2 learners studied but failed the test.
60 learners failed the test without having studied.
What is the probability that Brian will fail the test, given that he studied?

Answer 1

Answer:

2/130 or 1/65

Step-by-step explanation:

64+4+2+60 (all the people) =130

Given the fact that ''2 learners studied but failed the test.'' Brian is the same.

So you would do 2/130 or simplify it, 1/65.

Hope it helps :)
