Probability and Combinations in Coin Flips

The video tutorial explains the concept of probability using coin flips. It covers calculating total possible outcomes, understanding combinations and permutations, and applying formulas to determine the probability of specific outcomes, such as getting exactly 3 heads in 8 coin flips.

What is the main problem discussed in the video?

• Calculating the probability of getting 3 heads in 8 coin flips

• Exploring different types of coins

• Understanding permutations and combinations

• Learning about factorials
