Answer



The set of all 9 possible outcomes (sample space) for “f” and “m” combinations (f,m) is:




The set of all 9 possible outcomes (sample space)





There are only 2 outcomes where f is a factor of m.


 There are only 2 outcomes where f is a factor of m.
<br>






The probability that f is a factor of m = two out of nine

Probability = 2/9 = .22

Final Answer:

Probability = 2/9 = .22
