[AI-generated answer — Bot GPT 3.5]

Since a six-sided number cube has an equal probability of landing on any number from 1 to 6, the probability of rolling an even number is 3/6 or 1/2.

Therefore, out of 30 rolls, you can expect to roll an even number approximately 1/2 of the time, or 30 * 1/2 = 15 times.
