Question 1202343
.
<pre>

Another way to solve the problem is to calculate the total number of the tackes first, 5 + 7 = 12,


and then to write an expression for the probability

    P = {{{(7/12)*(6/11)*(5/10)}}} = reduce the fractions and get the answer = {{{(7/2)*(1/11)*(1/2)}}} = {{{7/44}}}.    <U>ANSWER</U>


The formula is SELF-EXPLANATORY and, therefore, does not requires explanations.

Solved.
