<PRE><B>Question 1204155</B>
.


Too many questions in one post. &amp;nbsp;I will answer &amp;nbsp;(a) &amp;nbsp;and &amp;nbsp;(d), &amp;nbsp;ONLY.


&lt;pre&gt;
(a)  P = 0.85^7 = 0.3206  (rounded).    &lt;U&gt;ANSWER&lt;/U&gt;


(d)  P = (1-0.85)^7 = 0.15^7 = 1.70859E-06   (rounded).    &lt;U&gt;ANSWER&lt;/U&gt;
&lt;/pre&gt;


For all other cases, &amp;nbsp;use standard formulas for binomial distribution.
