If I flip a coin and it comes up Heads...?

Question

I will praise Jesus and raise 10 Christian kids.

And if it lands tails.... I will quietly live out the rest of my life, childless.

1000 of my friends have this same plan: They will praise Jesus and have 10 Christian kids if their coin lands Heads.

All of the kids born as a result of a coin landing Heads, will go and do the same coin toss as their parents did, and so will their children's children, and so on...

10 generations down the line, how many people in the world, on average, will believe that Jesus made their ancestor's coin land Heads, and that their lineage is the chosen one?

Answer 1

I have some trick "tails only" quarters you can borrow... ;)

Answer 2

Hmm, the assumption is that the probability of landing heads is 1 out of 2. So, for the first generation, there will be 500 more or less landing heads and bearing 10 children which makes the 2nd generation number to 5,000 assuming all of them are fertile and would be within child-bearing age til they reach child number 10 and assuming further that their children were fathered/bore by a partner not member of that group and that no sick father ****** their daughter.

Using the same assumptions, the 3rd generation would number 25,000.

4th: 125,000
5th: 625,000
6th: 3,125,000
7th: 15,625,000
8th: 78,125,000
9th: 390,625,000
10th: 1,953,125,000

I had a difficulty with your question because it concerns all people inthe world and not the coin flipping bastards because one of my assumptions is that they will bore children from outside the group.

anyway, simplifying our lives, let us disregard that problem. If we ask those. 1.9 billion your question, they will answer only "yes" or "no" (for believing that Jesus made their ancestors' coin land heads, thereby making the probability of theanswer 1 out of 2) and "mine" and "not mine" (for assuming that their lineage is the chosen one, with the same probability)

So for both survey questions, the answer will be 976,562,500 each.

(What I would do for two points!)

oops, I started counting the generation at the children of the first ten. But I would not recompute.

Answer 3

None. noone who praises Jesus for being Jesus would believe He made a coin land a certain way. IMHO, God doesn't do things like that, if He was to play a part in the way the coin would land, He'd let it land on the side along the circumference, coz you believing in Him is entirely up to you, hence "free-will". Besides, you can't force your kids to do something you did yourself, let alone believe it to such an extent as to let their kids do the same and so on

Answer 4

Every 500 people (on average) will raise 10 kids each.
Let's, for the sake of argument, assume they don't intermarry, so if one of these kids decides to raise 10 of his own, then another kid can't also count those as her own.
So every generation increases its population 5 fold.
So from 1000 founders you get 5000 children.
They produce 25000 children.
They produce 125000 children.
They produce 625000 children.
This question should have been asked in Math, not in religion.
Well, and so on, to 5^10 = 9765625000 children, which clearly indicates that there WILL be intermarrying.

So, purely mathematical, that's 9.7 billion people who will all cast from heaven and go straight to hell, for gambling.

Answer 5

10 generations down the line all the families will be extinct just like everyone else on the planet.
Current world population 6.5 billion projected population in 2050 9 billion. Exactly how long do you think the human race has at that rate.

Answer 6

How many? Well, thats just a matter of chance. A flip of the coin as they say.

Answer 7

If it doesn't work they would only say that satan influenced the coin anyway.

Answer 8

All of them. Thats the way it works dont you know.

Answer 9

lol, funny but it`s true...that`s exactly what they`ll believe...

Answer 10

.....and your point is?
