Question

what does a 100% probability indicate about an event in environmental conservation?
a. the event has already happened
b. the event is certain to happen
c. the event is unlikely to happen
d. the events outcome cannot be predicted

Explanation:

Probability measures the likelihood of an event. A 100% probability means the event is sure to occur. Option a is wrong as probability is about future likelihood, not past. Option c is incorrect as 100% is the highest likelihood. Option d is wrong as 100% probability implies a definite prediction.

Answer:

B. The event is certain to happen
