How many of the products are less than
or equal to +40+ ?
A -- B -- C
--------------
1 -- 4 -- 7
1 -- 4 -- 8
1 -- 4 -- 9
1 -- 5 -- 7
1 -- 5 -- 8
--------------
+5+ products are less than or equal to +40+
--------------
The number of possible products is:
+3%2A3%2A3+=+27+
Products that are greater than +40+ are
+%28+27+-+5+%29+%2F+27+
+22%2F27+
This is the probability that the product will
be greater than +40+
