Question 1147923
.
<pre>

Having nothing else given, an appropriate hypothesis is to assume that we have integer random variable 



    X = "the number of daily sales TVs at Best Buy" 



with random values that are uniformly distributed with the minimum value of 0 and the maximum value of 10 hours.



Then the mean average  is exactly 5 = {{{(0+1+2+3+4+5+6+7+8+9+10)/11}}} = {{{55/11}}}, as the problem states, 

and  the condition becomes "consistent with the given part" and "self-closed".



Then the probability  P(X = 10) = {{{1/11}}}.    <U>ANSWER</U>

Solved.
