Discrete or continuous distribution

Question

1. Determine whether each of the following would be a discrete or continuous distribution.

Answer 1

Here we need only to determine the meaning of the words "continuous" and "discrete."

1. Continuous means there are no interruptions in the possible values. Consider it to be no fractions. You can have 1 lightening strike, 2 lightening strikes, but you cannot have 1.5 lightening strikes.
2. Discrete simply means not continuous. It means there are values that don't make sense.

Applying this allows us to conclude that (a) is discrete, (b) is continuous and (c) is discrete
