Question: 1 / 400

Which of the following snippets will not simulate a random number between 1 and 1,000,000?

(long) (Math.random() * 1000001 + 1)

(long) (Math.random() * 1000000 + 1)

(long) (Math.random() * 999999 + 1)

The correct choice indicating which snippet will not simulate a random number between 1 and 1,000,000 is based on understanding how the `Math.random()` function operates. The function generates a random double value greater than or equal to 0.0 and less than 1.0.

In the choice provided, (Math.random() * 999999 + 1) generates a value that ranges from 1 to just under 1,000,000. Specifically, the smallest value produced would be when `Math.random()` returns 0.0, resulting in 1, and the largest value would be just under 1,000,000 when `Math.random()` approaches 1.0, which means you won't ever reach exactly 1,000,000. Therefore, this snippet does not cover the entire range up to 1,000,000.

In contrast, the other choices, which multiply by 1,000,000 and include 1 or by 1,000,000 and approach it with up to 1,000,000 but starting at 1, are correctly set up to simulate a complete range between 1 and 1,000,000. Snippets A and B include 1
