Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable. (a) The number of hits to a Web site in a day. (b) The amount of rain in City Upper B during April. (a) Is the number of hits to a Web site in a day discrete or continuous?

a) So the number of hits to a website is a discrete value that can assume any natural value from greater or equal to 0.

b) So the amount of rain in City Upper B during April is a continuous(real set) value ranging from 0 to infinite.

Step-by-step explanation:

Continuous:

Real numbers, can be integer, decimal, etc.

Discrete:

Only integer(countable values). So can be 0,1,2...

(a) The number of hits to a Web site in a day.

A website either has no hits, 1 hit, 2 hits, ..., that is, countable values.

So the number of hits to a website is a discrete value that can assume any natural value from greater or equal to 0.

(b) The amount of rain in City Upper B during April.

No rain, 0 units

We can have, 1.5 inches, 20 inches(using inch as an example of unit), that is, real numbers.

There is no negative amount of rain.

So the amount of rain in City Upper B during April is a continuous(real set) value ranging from 0 to infinite.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
