A Doozy of a probability question. This one has my head spinning!

A college administration has conducted a study of 169 randomly selected students to determine the relationship between satisfaction with academic advisement and academic success. They obtained the following: Of the 74 students on academic probation, 43 are not satisfied with the advisement; however, only 18 of the students not on academic probation are dissatisfied with advisement. What is the probability that a student selected at random is on academic probation and is not satisfied with advisement?

probability tree might come in handy

you need to find : P(not satisfied | academic probation)

right ?

It helps if you draw a 2 way table

Yes  P(not satisfied | academic probation)

unless the question is asking about "sampling distribution" and finding the pvalues, 
its a simple proability tree/contingency table problem

ganeshie8 · Answer

heard of any of them before ?
