Probability & Computing Problem Solving Series | Mitzenmacher & Upfal | Exercise 1.1 a | Let's solve

This is the beginning of Probability Problem Solving series. We solve the exercise questions in the textbook "Probability and Computing" by Michael Mitzenmacher and Eli Upfal.
In this video, we solve the exercise 1.1 a question. What is the probability of the event that number of heads = number of tails, where the experiment is tossing coin 10 times. Let's solve.

we can use Binomial Distribution so 2nCn*(1/2)^n*(1/2)^n
2nCn*(1/2)^2n

That's fine, we can directly apply binomial distribution formula. I was actually focusing on the concept behind the formula.
