Probability of Rolling Two Dice

The video tutorial explains how to calculate the probability of rolling two dice and getting a sum of seven. It begins by defining the total number of outcomes using the counting principle, which results in 36 possible outcomes. The tutorial then identifies the favorable outcomes that result in a sum of seven, which are six in total. The probability is calculated as 6/36, simplified to 1/6. The video also demonstrates how to express this probability as a decimal and a percentage. Finally, it discusses the concept of probability within the range of 0 to 1 and explains that a probability of 1/6 means the event is unlikely but not impossible.
