Question 1153809
.
<pre>

P = {{{(C[22]^2*C[16]^2)/C[22+16]^4}}}


{{{C[22]^2}}} = {{{(22*21)/2}}} = 231;

{{{C[16]^2}}} = {{{(16*15)/2}}} = 120;

{{{C[38]^4}}} = {{{(38*37*36*35)/(1*2*3*4)}}} = 73815;


    P = {{{(231*120)/73815}}} = 0.3755.      <U>ANSWER</U>
<U>ANSWER</U>

------------------


I agree with critics by Edwin.


I just took off that part of my solution, which was incorrect.


I also expanded the first part of my solution, placing calculations explicitly, and got the same answer for the probability, 

as Edwin got.


So now you see the corrected version in my post.



Thanks to Edwin for his note (!)
