```

```elixir
# Random key seed
k = Nx.Random.key(1)
# roll 1000 dice with a shape of 1x1000
{dice_rolls, _} = Nx.Random.randint(k, 1, 6, shape: {1000})

# 2.96
Nx.divide(Nx.sum(dice_rolls), 1000)
# or
# 2.96
Nx.mean(dice_rolls)

# {1000} vector dice_roll*dice_roll
Nx.multiply(dice_rolls, dice_rolls)
# 10.85
|> Nx.mean()
```

```elixir
Nx.tensor([
  [1, 2, 3, 4, 5],
  [12, 22, 32, 42, 52]
