Question

From Environment Canada: "Our experts on weather and climate have combed through 45 years of weather records, and determined the probabilities based on the following criteria: -a "white" Christmas is defined as having at least 2 cm of snow on the ground on December 25." The probability that there will be a white Christmas in Vancouver is 11%. The probability that there will be a white Christmas in Hamilton is 68% What type of probability have they used to determine these probabilities? Theoretical Conditional Experimental Subjective

From Environment Canada: "Our experts on weather and climate have combed through 45 years of weather records, and determined the probabilities based on the following criteria: -a "white" Christmas is defined as having at least 2 cm of snow on the ground on December 25."

The probability that there will be a white Christmas in Vancouver is 11%.
The probability that there will be a white Christmas in Hamilton is 68%

What type of probability have they used to determine these probabilities?
Theoretical
Conditional
Experimental
Subjective

Answer 3

old question, answering so this can be closed

notice how they used *existing* outcome data to determine what the likelihood of having a white Christmas was. on a simple level, they counted the # of days that counted as a white christmas, and divided them by total # of days (or a similar calculation). this matches with the idea of experimental probability.
