n is an integer chosen at random from the set
{5, 7, 9, 11 }
p is chosen at random from the set
{2, 6, 10, 14, 18}
What is the probability that n + p = 27 ?  Choose the correct choice.
A) 0.1  B) 0.2  C) 0.25  D) 0.3  E) 0.05
Set N: there is 4 ways to chose a number   Set P: there is 5 ways to chose a number   so total outcome is  4*5= 
<gadget id="calculator"> 4*5</gadget>
<output>20</output>
20 which is represent 20 pairs of number   now we have 1 pairs can give us 27 which are (9,18)   1/20= 
<gadget id="calculator">1/20</gadget>
<output>1/20 = around 0.05</output>
0.05   Answer 0.05
<result>E</result>
