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 = 25 ?
Choose the correct choice from the following options: A) 0.1 B) 0.2 C) 0.05 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 1 pairs can give us 25 which are (11,14) .   1/20= 
<gadget id="calculator">1/20</gadget>
<output>1/20 = around 0.05</output>
0.05   Answer 0.05
<result>C</result>
