**IGNOU probability**

Make 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...
