Question 1160128
.


Dear student @saw


from your post I see that


<pre>
    - you don't know the basics of the probability theory

    - you didn't get the meaning of this problem / (of this assignment)

    - you were not able to distinct questions from answers

          (to help you to make this distinction, let me say, that there is NO ANSWERS in this post --- there are QUESTIONS only).
</pre>

I am afraid that with such level of knowledge, &nbsp;<U>there is &nbsp;NOTHING &nbsp;TO &nbsp;DO &nbsp;for you at this forum as a tutor</U>.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Did I say  &nbsp;"I am afraid" ?   ---   &nbsp;Ooo, &nbsp;not, &nbsp;sorry.  &nbsp;&nbsp;I am &nbsp;179% &nbsp;confident.
