Both events have the same likeliness of happening.
Step-by-step explanation:
A number cube has 6 numbers and 3 of them are even so the probability of rolling an even number is 3/6, which is 1/2. A coin has two sides, so the probability of flipping a coin heads up is 1/2. Rolling an even number on a number cube and flipping a coin heads up both have a 1/2 probability.
