n is an integer chosen at random from the set
{1, 5 , 9, 11 }
p is chosen at random from the set
{2, 6, 10, 14, 18}
What is the probability that n + p = 15 ?	Choose the correct choice from the following answers:	A) 0.1	B) 0.2	C) 0.15	D) 0.3	E) 0.4
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=

<output>20</output>
20 which is represent 20 pairs of number   now we have 3 pairs can give us 15 which are (1,14),(5,10) and (9,6) .   3/20=

<output>3/20 = around 0.15</output>
0.15   Answer 0.15
<result>C</result>
