Question 1182082
.
​22% adults favor the use of unmanned drones by police agencies. Twelve U.S. adults are randomly selected. 
Find the probability that the number of U.S. adults who favor the use of unmanned drones by police agencies is​ 
(a) exactly​ three, (b) at least​ four, (c) less than eight. 

(a)P(3)=(Round to three decimal places as​ needed.)
​(b)P(x≥4)=(Round to three decimal places as​ needed.)
​(c)P(x<8)=(Round to three decimal places as​ needed.
~~~~~~~~~~~~~~~~~~~



As the problem is worded, printed, &nbsp;posted and presented, &nbsp;it is formulated &nbsp;INCORRECTLY.



Below I place a correct formulation as this problem &nbsp;SHOULD &nbsp;SOUND.


<pre>
    ​22% adults favor the use of unmanned drones by police agencies. Twelve U.S. adults are randomly selected. 
    Find the probability that <U>of the selected 12 adults</U> the number of those who favor 
    the use of unmanned drones by police agencies is​ 
    (a) exactly​ three, (b) at least​ four, (c) less than eight. 

    (a) P(3)=(Round to three decimal places as​ needed.)
​    (b) P(x≥4)=(Round to three decimal places as​ needed.)

Do you see &nbsp;(or do you feel) &nbsp;the difference ?



Looking into your post, &nbsp;I clearly see that you &nbsp;DO &nbsp;NOT &nbsp;UNDERSTAND &nbsp;what you post,
and it makes me sad.


I also see that your writing is not an accident typo&nbsp;: &nbsp;&nbsp;in your next post &nbsp;(problem 1182086), &nbsp;you make the same mistake.


So, &nbsp;EITHER &nbsp;you take your problems from the bad source, &nbsp;which does not deserve &nbsp;TRUST;

OR &nbsp;you create/compose the problems on your own without understanding the real meaning of the problem.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It would be interesting for me to know from you, &nbsp;which one of these two versions takes place.



In any case, &nbsp;by seeing so deep misunderstanding from your side, &nbsp;I can not continue. 



My task at this forum is to teach, but in order for to be successful, 
I should see minimal understanding of the subject from the visitor' side.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Which I do not see in your post.
