<PRE><B>Question 1200048</B>
.


In the post by @Theo, &amp;nbsp;his picture for the problem &amp;nbsp;(a) &amp;nbsp;is incorrect
(actually, &amp;nbsp;his figure for problem &amp;nbsp;(a), &amp;nbsp;OBVIOUSLY, &amp;nbsp;does &amp;nbsp;relate to problem &amp;nbsp;(b)&amp;nbsp;).


But the number &amp;nbsp;(the probability 0.1733) &amp;nbsp;is correct, &amp;nbsp;as &amp;nbsp;I &amp;nbsp;checked it.
