Yes!

#### Explanation:

A good example is the **Binomial** distribution. As long as the following condition is met:

np and n(1-p) are both greater than 5, you can use the continuous **Normal** distribution to approximate the Binomial.

Other discrete distributions such as the **Poisson** can also be approximated using the Normal.
