Which expression maps Math.random() to an integer in the closed interval [minimum, maximum] when both bounds are valid integers?

1. minimum + Math.floor(Math.random() * (maximum - minimum + 1))
2. minimum + Math.round(Math.random() * (maximum - minimum))
3. Math.floor(Math.random() * maximum) + minimum
4. minimum + Math.ceil(Math.random() * (maximum - minimum + 1))
