Question

1. a probability of 0.1 means the event is: impossible a unlikely b likely c certain d

Explanation:

To determine the description of an event with a probability of 0.1, we recall probability interpretations: An impossible event has a probability of 0, a certain event has a probability of 1. Probabilities between 0 and 0.5 (closer to 0) are considered unlikely, and between 0.5 and 1 (closer to 1) are likely. Since 0.1 is between 0 and 0.5 and closer to 0, the event is unlikely.

Answer:

B. Unlikely
