Determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. the amount of rain in city upper b during april b. the number of points scored during a basketball game c. the eye color of people on commercial aircraft flights d. the number of fish caught during a fishing tournament e. the number of statistics students now reading a book f. the exact time it takes to evaluate 27 plus 72

a. The amount of rain in City Upper B during April: Continuous Random Variable.

Since, we can't count the random variable and its value lies between two discrete random variable. For Example: 42.2 ml

b. The number of points scored during a basketball game: Discrete Random Variable.

Since, we can count them.

c. The eye color of people on commercial aircraft flights: Not a Random Variable.

Since, It does not has a numerical random variable. For Example: Blue, brown, etc.

d. The number of fish caught during a fishing tournament:  Discrete Random Variable.

Since, we can count them. for Example, 5 fish, 4 fish,etc. we can't written it as 4.5 fish.

e. The number of statistics students now reading a book: Discrete Random Variable.

Since, we can count them. for Example, 5 fish, 4 fish,etc. we can't written it as 4.5 fish.

f. The exact time it takes to evaluate 27 plus 72: Continuous Random Variable.

Since, we can't count time. Some can take time as 1.2 minute, 0.48 second, etc.

Option B

Step-by-step explanation:

For answering this question we must understand what is a function.

A function is different from mapping.

Mapping is just a subset of AxB where A and B are two sets.

But function is constrained to the point that elements of I set will have unique image in second set.

We find From the options

But in option B,, we find that 1 has two images 3.3 and 4.5.  i.e. 1 does not have unique image. Hence not a function.

All other options the first element in ordered pair have a unique image.

Hence all other options are functions.

Only option B is not a function.
