Determine whether the random variable is discrete or continuous. a. The time it takes for a light bulb to burn out. b. The height of a randomly selected giraffe. c. The number of people with blood type Upper A in a random sample of 39 people. d. The number of fish caught during a fishing tournament. e. The exact time it takes to evaluate 27 plus 72.

Step-by-step explanation:

A continuous random variable is a random variable where the data can take infinitely many values. Examples include height, weight, the amount of sugar in an orange, the time required to run a mile.

A discreet random variable has a countable number of possible values. The probability of each value of a discrete random variable is between 0 and 1, and the sum of all the probabilities is equal to 1. It is a countable number of distinct values such as 0,1,2,3,4, ... Discrete random variables are usually (but not necessarily) counts.

therefore from the option given

a. The time it takes for a light bulb to burn out.

Continuous random variable because it can take infinitely many values. the time cannot be counted

b. The height of a randomly selected giraffe.

Continuous random variable

c. The number of people with blood type Upper A in a random sample of 39 people.

A discreet random variable because the value of the people is given which means it can be counted

d. The number of fish caught during a fishing tournament.

A discreet random variable

e. The exact time it takes to evaluate 27 plus 72.

A discreet random variable
