Hi there,
I am wanting to use something like
```julia
rand.(Normal.([5;10],1),1)
```
where we have two different mean values \mu\_1=5, \mu\_2=10 which we broadcast over to generate 2 random numbers total. I would like the output to be a 2-element vector, where each element of the vector is a float64, but instead it returns a 2-element vector, which each element being a 1-element vector.
Example of current output:
```julia
2-element Vector{Vector{Float64}}:
[5.660588027201526]
[10.557198737804264]
```
Thanks in advance.

`rand()` creates a single random value, whereas `rand(, 1)` creates a 1-vector of random values. Therefore, you just have to remove the last argument of the broadcasted `rand`:
```julia
rand.(Normal.([5;10],1))
```

Brilliant, thanks!
