wat 

 

false

 

its just gamblers fallacy rite?

[Arctic]

Is it just me or are there two questions?

[Aza]

1/2*1/2 is 1/4

then count the 2 losses = 1/16

1/16 chance you'd win exactly 2 games.

Just saying, I'm not the best at statistics and probabilities.

 

Now, saying that you'd win exactly half, I can't seem to work that part out. I'm going to say false though, based on logical thinking.

4^2 = 16 total outcomes.

 

4 ways of winning exactly 2.

 

4/16 = 1/4

 

False.

i was about to post that you fked that calculation up

Yeah, i was working out the probability of winning 2 or more.

Silly me

[Caam]

4C2*(0.5)^4

 

 

so 3/8

[YinZ]

4C2*(0.5)^4

 

 

so 3/8

 

I believe this is correct
