Question 1192110
.
An experiment  succeeds thrice as after it fails 
if experiment is repeated 5 times what is the probability of having no success at all?
~~~~~~~~~~~~~~~~


<pre>
If I understand this message correctly, it tries to tell that in this binomial experiment the probability of success is 3/4.


If my guessing is correct, then the probability under the problem's question is

    P = {{{(1-3/4)^5}}} = {{{(1/4)^5}}} = {{{1/4^5}}} = {{{1/1024}}}.    <U>ANSWER</U>

Solved.
