A ball is drawn at random from a box containing 6 red, 4 white, and 5 blue balls.
Find the probability that
(a) it is red
(b) it is white
(c) it is blue
(d) it is not red
(e) it is red or white
~~~~~~~~~~~~~~~~~~


                    - - - See how I edited your writing - - -


(a)  P = 6%2F%286%2B4%2B5%29 = 6%2F15 = 2%2F5.


(b)  P = 4%2F15.


(c)  P = 5%2F15 = 1%2F3.


(d)  P = %284%2B5%29%2F15 = 9%2F15 = 3%2F5.


(e)  P = %286%2B4%29%2F15 = 10%2F15 = 2%2F3.


I solved everything and wrote everything.

From my solution, everything should be CLEAR to you without any additional explanations.

Hope, in the future, you will be tackle similar simple problems without any difficulties.

The theory behind it is in these two lines

    +------------------------------------------------------------------+
    |   Probability is the ratio of the number of favorable outcomes   |
    |        to the total number of all possible outcomes.             |
