Well if it was increased from last year, then it must be dealing with devision to find out the price of last year...
So when you divide the number 287.50 by 15% You get to the total of:
<span>1 916.66667
</span>So your answer is: <em>$1,916.67 </em>
Begin by computing the number of all the possibilities:
It is given by the following formula:

Computing the number of favorable cases:
Exactly one pair of socks with the same color means either one magenta pair,
or one cyan pair, or one black pair or one white pair:
Number of possibilities with one magenta pair means"a magenta pair plus two socks with different colors from three possibilities" means 3 possibilities.
Same computation for the other colors.
Adding we get:

By definition, the probability of an event is the number of favorable cases over the number of possible cases:
The probability is
