r, British Columbia, the probability of rain during a winter day is 0.58, for a spring day it is 0.38, for a summer day it is 0.25 and for a fall day it is 0.53. Each of the four seasons lasts one quarter of the year. What is the probability of rain on a randomly chosen day in Vancouver? The answer should be a number between 0 and 1. How to know which probability formula to use?

In Vancouver, British Columbia, the
How to know which probability formula to use?
