Question 960788: a box containing 11 marbles with labeled 0 tp 10. A marble is selected from the box randomly. find the probability distribution of X representing the number on the marble that is drawn. what is the probability that the number drawn is
a) less than 3;
b) at least 7;
c) between 2 and 6 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! a box containing 11 marbles with labels 0 to 10.
A marble is selected from the box randomly. find the probability distribution of X representing the number on the marble that is drawn.
Mean = (1/11)(0+1+2+...+10) = (1/11)(11/2)(0+10) = 5
std = 3.3166
------------------------
what is the probability that the number drawn is
a) less than 3; 3/11
------------------
b) at least 7; 4/11
------------------
c) between 2 and 6
If 2 and 6 are included:: 5/11
If 2 and 6 are not included:: 3/11
