Detailed explanation-1: -A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.

Detailed explanation-2: -An example of this is tossing a coin as there is an equal or even chance of landing on heads or tails. If there is less than an even chance of an event occurring, we say it is unlikely to happen. In a similar way, if the chance of an event happening is greater than an even chance, we say it is likely to happen.

Detailed explanation-3: -An unlikely event would have a probability between 0 and ½. A likely event would have a probability between ½ and 1.

Detailed explanation-4: -Unlikely means there’s a small chance that an event will happen. Likely means there’s a big chance that an event will happen.
