**drwls**, Friday, October 15, 2010 at 6:22amMake a Venn diagram.

5% fail math only

25% fail both

10% fail stats only

60% pass both.

Of the 30% (of all students) who failed math, 5/6 of that group (25% of all students)failed stats also. That is a conditional probability of 83.3%. Only 16.7% of the math-failing group pass stats.
