Final answer:
A 60% chance of rain means C. there is a 60% probability that rain will occur on that day.
Step-by-step explanation:
Probability is a measure of the likelihood of an event occurring, expressed as a value between 0 and 1. A probability of 0 indicates impossibility, 1 signifies certainty, and values in between represent varying degrees of likelihood. It plays a crucial role in statistics, decision-making, and risk assessment.
When a meteorologist predicts a 60% chance of rain, it means that there is a 60% probability that rain will occur on that day. This percentage represents the likelihood of rain happening based on the meteorologist's assessment of atmospheric conditions. It does not indicate the duration of rainfall or the number of times it will rain.
