Question 1142499
.
<pre>

If to assume that these two events are INDEPENDENT, then the probability that both events will happen is the product 

of individual/partial probabilities


    P = {{{3/4}}}.{{{3/7}}} = {{{9/28}}}.


Without such assumption, the problem can not be solved, at all.


But validity of the assumption itself is questionable, in real life.

---------------


Let me tell you slightly more about this problem.


Behind each probability problem, &nbsp;there is, &nbsp;actually, &nbsp;<U>an experiment</U>.


At least, &nbsp;a &nbsp;MENTAL &nbsp;experiment.


Now, &nbsp;could you imagine any <U>real life</U> experiment behind &nbsp;THIS &nbsp;problem ?



It is why this problem can be considered as a joke &nbsp;ONLY&nbsp;: &nbsp;&nbsp;ONLY &nbsp;in its &nbsp;<U>joking mode</U>.
