Answer:
The answer is a well designed experiment.
Step-by-step explanation:
When possible, the best way to establish that an observed association is the result of a cause and effect relation is by means of - well designed experiment.
Cause and effect relation is a relation between events, where one is the result, due to the occurrence of others. A well designed experiment takes place when we consider the cause and effect of events.

Let be 0 the sea level.
Since the heron is perched in a tree 50 feet above sea level and directly below the heron the pelican is flying 17 feet above sea level, you can find the difference in height between the pelican and the heron by subtracting 50 feet from 17 feet.
Then, you get that this is:

Now, according the the information given in the exercise, you know that the trough is swimming directly below them and its height is 23 feet below sea level. If you represent this with an integer, this is:
Therefore you can find the difference in height between the pelican and the trout through the following subtraction:
And the distance between them is 40 feet too.
Answer: (a) 19448 ways
(b) 5292 ways
(c) 0.2721
Step-by-step explanation:
(a) 10 county council members be randomly elected out of the 17 candidates in the following ways:
= 
= 
= 
= 19448 ways
(b) 10 county council members be randomly elected from 17 candidates if 5 must be women and 5 must be men in the following ways:
we know that there are 7 women and 10 men in total, so
=
× 
=
× 
= 21 × 252
= 5292 ways
(c) Now, the probability that 5 are women and 5 are men are selected:
= 
= 
= 0.2721
