Probability and Outcomes with Coins

The video tutorial explains how to calculate the probability of getting exactly two heads when flipping three coins. It begins by discussing the concept of sample space and lists all possible outcomes of the coin flips. The tutorial then identifies the outcomes that result in exactly two heads and calculates the probability by dividing the number of favorable outcomes by the total number of possible outcomes, resulting in a probability of 3/8.
