get scholarship and 0.75 that he/she will graduate. If the probability is 0.2 that he/she will get
scholarship and will also graduate. What is the probability that a student who get a scholarship
graduate?
~~~~~~~~~~~~~~~


<pre>
It is the ratio of the probability  P(get a scholarship AND graduate) to the probability 

P(get a scholarship)   (so called conditional probability)


    the probability that a student who get a scholarship graduate = {{{0.2/0.25}}} = {{{4/5}}} = 0.8 = 80%.        <U>ANSWER</U>
