Anyway, so let's do a slightly harder problem than we did before. We were dealing with fair coins. Let's deal with a slightly unfair coin. Let's say I have a coin, and it's a, actually instead of unfair coin, let's do basketball. Let's say I'm shooting free throws, and I have a free throw percentage of 80%. So when I shoot a free throw 8 out of 10 times, or 80% of the time, I will make it. But that also says that 20% of the time, I will miss it.
