Suppose we are given the following table of data. This tells us whether or not our friend will play a game of chess with us outside in the park, based on a number of weather-related conditions:
Temperature |
Wind |
Sunshine |

We would like to establish, by using Bayes' theorem, whether our friend would like to play a game of chess with us in the park given that the Temperature is Warm, the Wind is Strong, and it is Sunny.
