Question 1157047
.
<pre>

(B)  16 + 12 + 8 = 36


     P(one is oatmeal, other is ginger) = P(first is oatmeal, second is ginger) + P(first is ginger, second is oatmeal) = 

                                        = {{{(16/36)*(8/35)}}} + {{{(8/36)*(16/35)}}}.


     I showed you the structure of the formula.

     The formula itself is SEMI-EXPLANATORY.

     You complete calculations to get the value ON YOUR OWN.




(B)  7 + 4 + 7 + 6 = 24.


     P = P(red) + P(green) + P(blue) = {{{7/24}}} + {{{4/24}}} + {{{7/24}}}.



     I showed you the structure of the formula.

     The formula itself is SEMI-EXPLANATORY.

      You complete calculations to get the value ON YOUR OWN.



(C)  P = {{{seniors/(all_in_the_band)}}} = {{{27/215}}}.

Solved.  All questions are answered.
