Question 1165577
.
A coin flip determines who gets the ball first at the beginning of a football game, 
with the visiting team calling heads or tails. The captain of one particular team 
always calls for heads. In the first four games as a visitor of a season, 
find the probability that his team wins the toss more than once.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
In this problem, the experiment is tossing the coin 4 times with the probability of success
at each individual tossing p = 0.5 (getting the head).


In all, the experiment has  {{{2^4}}} = 16 different independent outcomes.


The favorable outcomes of the experiment are getting the head more than once in 4 tossing.


The complementary outcomes are getting the head 0 or 1 time in 4 tossing.



        There are 1+4 = 5 possible complementary outcomes (TTTT, HTTT, THTT, TTHT, TTTH).



Therefore, the complementary probability is  {{{5/16}}}.

Hence, the probability under the problem's question is  {{{1 - 5/16}}} = {{{11/16}}}.    <U>ANSWER</U>
