It is a continuous random variable. O C. It is not a random variable c Is the eye color of people on commercial aircraft fights a discrete random variable, a continuous random variable, or not a random vaniable?

Explanation / Answer

b.

a. Continuous random variable. .

Since the height can take any numerical value and provisions have been made to ensure that the selection is random, this must be a continuous random variable.

b. Discrete random variable

The number of fish caught must take only positive integer values and hence it is discrete.

c. Not a random variable

The eye color can take values such as black, brown etc and not quantitative numerical values, hence it is not a random variable.

d. Continuous Random Variable

Weight can take continuous values.

e. Continuous random variable

The amount of rain can be measured in mm2 or cm2 and it can take any value.

f. Continuous random variable.

In categorizing this as a continuous random variable , I am assuming that this time taken to do calculation is by different persons.
