Question 806239: Many students entering unversity take a math course, 1J03.
In this course, 9% of the students fail, and leave the university.
29% of the students pass, but get a low mark, and move on to 1E03.
62% of the students pass, and get a high mark, and move on to 1KR3.
In 1E03, 14% fail, and leave the university. In 1KR3, 21% fail, and depart.
If a student tells his parents he failed mathematics and had to leave the university, what is the probability that he failed out of 1E03?

You can put this solution on YOUR website! .29*.14=.0406 flunked out of 1E03
.62*.21=.1302 flunked out of 1KR3
.09 flunked out of 1J03
.
.0406+.1302+.09=.2608
.0406/.2608
=.1557 the probability that he failed out of 1E03.
