Explanation:
To determine which event is neither likely nor unlikely to occur, we should consider the probability of each event:
A new school year is scheduled to start on the 18th of the month.
This event is either certain or impossible depending on the school's schedule. It's not a matter of probability.
An even number is rolled on a number cube numbered from 1 to 6.
There are three even numbers (2, 4, 6) out of six possible outcomes. So, the probability is 3/6 or 1/2, which is considered equally likely or 50/50.
A randomly selected house has a house number that is a multiple of 10.
The likelihood of this depends on the numbering system of the houses and the total number of houses. It's not generally predictable and varies greatly based on location and the total number of houses.
A certain raffle ticket is pulled from a bag containing 30 different tickets.
The probability of any specific ticket being drawn is 1/30, which is quite low. This is an unlikely event.
Based on these considerations, the event that is neither likely nor unlikely to occur would be rolling an even number on a number cube numbered from 1 to 6. This is because it has an equal probability of happening or not happening (50/50 chance). The other events are either certain, dependent on specific conditions, or unlikely.
,Hopefully that helps.
