Answer 1

The random variable is discrete if its values are countable and obtained by counting. The possible values of the random variables are...

Step-by-step explanation:

The random variable is discrete if its values are countable and obtained by counting. The possible values of the random variables are:

a. The number of light bulbs that burn out in the next week in a room with 20 bulbs: 0, 1, 2, 3, ..., 20

c. The number of hits to a website in a day: 0, 1, 2, 3, ...

d. The amount of snow in Toronto during the winter: Continuous random variable as it is measured and can take any value on a continuous scale.
