Yea, but you can do that with the Distributions example too:
julia> coins = Bernoulli.([0.2, 0.5, 0.7]) # 3 coins with different weights
3-element Array{Bernoulli{Float64},1}:
Bernoulli{Float64}(p=0.2)
Bernoulli{Float64}(p=0.5)
Bernoulli{Float64}(p=0.7)
julia> rand.(coins) # flip the set of coins
3-element BitArray{1}:
0
1
1
