How to find the conditional probability from a tree diagram

The video tutorial discusses a probability problem involving the likelihood of fog and a game being canceled. It explains how to calculate the probability of both events occurring by multiplying their individual probabilities. The probability of fog is given as 70%, and the probability of game cancellation is 30%. By multiplying these probabilities, the result is 21%, indicating the chance of both events happening together.

Explain the significance of the 70% probability mentioned in the text.
