AND and OR (beyond digits and letters) | Permutation and Combination | Grade 11| Math | Khan Academy

Описание: This video tackles the application of AND and OR beyond digits and letters. We talk about balls, coins, flags, and people. We first find the total number of arrangements of 3 types of balls. We then nominate President and Vice-president from a group of people. We find the total number of outcomes we can get if we toss a coin a specific number of times. Finally, we deal with scenarios where we create signals using 2 or more flags.
