Dtermine whether the following value is a continuous random​ variable, discrete random​ variable, or not a random variable.

a. The number of pigeons in a countrynumber of pigeons in a country

b. The hair color of adults in the United Stateshair color of adults in the United States

c. The number of home runs in a baseball gamenumber of home runs in a baseball game

d. The height of a randomly selected personheight of a randomly selected person

e. The number of free dash throw attempts before the first shot is missednumber of free-throw attempts before the first shot is missed

f. The time it takes to drive from City Upper A to City Upper Btime it takes to drive from City A to City B a. Is the number of pigeons in a countrynumber of pigeons in a country a dis

a) Discrete random variable

b) Not a random variable

c) Discrete random variable

d) Continuous random variable

e) Discrete random variable

f) Continuous random variable

Step-by-step explanation:

a) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

b) This is not a random variable because hair color is quality, thus it cannot be quantify.

c) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

d) This is continuous random variable because we can quantify it, it can take decimal number and has no true zero. For instance, 0 degree Celsius does not implies absence of temperature. Or that we say someone is a dwarf does not implies he/she has no height even though the measure scale may read zero.

e) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

f) This is continuous random variable because we can quantify it, it can take decimal number and has no true zero. For instance, 00:00 GMT does not implies absence of time.
