Step-by-step explanation:
Answer:
a. Continuous random variable
b. Continuous random variable
c. Discrete random variable
d. Discrete random variable
e. Continuous random variable
a.The time it takes to fly from City Upper A to City Upper B is a continuous random variable.
Step-by-step explanation:
- When the value of the variable is found by counting the variables, it is termed as a discrete variable.
- When the value of the variable is found by measuring the variables, it is termed as a continuous variable.
In (c) and (d), the values of the variables can be found by counting. The number of fish and the number of textbook authors can be counted. Hence, they are discrete random variable.
In (a), (b) and (e) the values can be found by measuring. The time taken to fly, the time taken for light to travel and the distance to travel are the variable that are measured. Hence, they are continuous random variable.
