Sir, I cannot thank you enough. I was petrified by this chapter but thanks to this I am relieved. However, just one little glitch- at 14:03, P(X>9) shouldn't it just be from k=10 to 12 as it asks greater than and not greater than equal to? Just wondering

What khushi lanker said. 10, 11, 12 since X > 9, not >= 9.
