n is an integer chosen at random from the set
{5, 7, 9, 11 }
p is chosen at random from the set
{2, 4, 10, 14, 18}
What is the probability that n + p = 13 ?  Choose the correct choice from the following choices:
A) 0.15
B) 0.2
C) 0.25
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 13 which are (7,6), (9,4) and (11,2) .   3/20= 
<gadget id="calculator">3/20</gadget>
<output>3/20 = around 0.15</output>
0.15   0.15nswer 0.15
<result>A</result>
