  • (0:01) Definition of Probability: Probability measures how likely an event is to happen, ranging from 0 (impossible) to 1 (certain), or from 0% to 100%.
  • (0:30) Basic Probability Calculation: Probability of an event = (Number of favourable outcomes) / (Total number of outcomes). For example, drawing a red ball from 10 balls, where 3 are red, has a probability of 3/10 or 30%.
  • (1:39) Experimental Probability: When exact values are unknown, estimate probability by repeating an experiment. More trials helps to get experimental probability closer to true probability values.
