Final answer:
The probability that the event occurs, with 16 equally likely outcomes and 8 ways for the event to occur, is calculated as 8 divided by 16, which equals 0.5 or 50%.
Step-by-step explanation:
To calculate the probability that an event occurs, we need to know two basic pieces of information - the total number of possible outcomes, and the number of ways the event can occur. Given that the experiment has 16 possible outcomes, all equally likely, and the event can occur in 8 ways, we simply divide the number of ways the event can occur by the total number of possible outcomes.
The calculation is as follows:
Probability = Number of ways the event can occur / Total number of possible outcomes
=
8 / 16
= 1 / 2
= 0.5
Therefore, the probability that the event occurs is 0.5, or 50%.
