Suppose we've initialized a random number generator from Numpy as
```
import numpy as np
rng = np.random.default_rng()
```
1. Generate and store 100 random numbers using rng into a variable named x.
2. Calculate the mean of x.
Suppose we have the following code.
```
a = np.zeros(shape = (3, 4, 5))
```
1. How many elements are in a?
2. How many dimensions are in a?
3. What are the lenghts of each dimension of a?
