<PRE><B>Question 1150193</B>
.
Suppose a math class contains 34 students, 21 females (three of whom speak French) and 13 males (two of whom speak French). 
Compute the probability that a randomly selected student speaks French, given that the student is female.
~~~~~~~~~~~~~~~~



&lt;pre&gt;
The answer is  MORE THAN OBVIOUS.


This probability is  {{{3/21}}} = {{{1/7}}}.    &lt;&lt;&lt;===---   &lt;U&gt;A N S W E R&lt;/U&gt;


It is because 3 of the 21 females speak French (given).


This part of the condition &quot; . . . given that the student is female&quot;  means that actually we select the random person &lt;U&gt;among women&lt;/U&gt;.


By using this interpretation, we get the solution  &lt;U&gt;EXTREMELY simple&lt;/U&gt;.
&lt;/pre&gt;

&lt;U&gt;Notice&lt;/U&gt;.  Tutor @Boreal misread the problem and got incorrect answer.
