Question 1204048
.


I will solve the second problem, ONLY, which is 4.6, 4.6.1, 4.6.2.



<pre>
4.6.1.  P = {{{(1/2)*(1/2)*(1/2)}}} = {{{1/8}}}.    <U>ANSWER</U>


        In wording form: in all, 8 outcomes are possible:

            (1)  H H H

            (2)  H H T

            (3)  H T H

            (4)  H T T

            (5)  T H H

            (6)  T H T

            (7)  T T H

            (8)  T T T

    Of them, only one outcome is favorable: it is (H H H).

    It gives the probability  {{{1/8}}}.




4.6.2.  In the list of possible outcomes above, 
        find all outcomes with two H and one T.

        There are three such outcomes.  They are  (2), (3) and (5).

        Therefore, the probability in this problem is  P = {{{3/8}}}.    <U>ANSWER</U>
</pre>

Solved.
