What are the odds?

[tikay]

I'm trying to answer a question for a friend of mine.

I don't even know how you measure the odds, or probability of such things, but if anyone can give me a steer on this, I'd appreciate it.

If we toss a coin 146 times, logically it should come down heads roughly half of the time. (73 times).

In fact, it came down 63-83, so "heads" was 10 flips out of sync.

How probable is this? How often (as a %, perhaps?) will it come down 63-83?

Sorry it's a bit vague, but there's good reason for asking.

It is actually, that was really a disguised "work" question.

Next Door do some 50/50 flip things, think they are called "Russian Roulette", they are used to gain Reward Points and are pure flips, 50/50 (minus rake).

A friend lost 63 out of 146 and wondered what the odds of that were, hence my question.

Customer service & all that.
