Title: throwing 8 coins - probability question
Post by: hanshuckebein on May 03, 02:43 PM 2019
hi folks,

following this explanation

link:s://:.youtube.com/watch?v=vkYsmIlM9CE

throwing  8 coins the probability of getting 5 heads and 3 tails is 0.218,

my question: what is the probability of getting either 5 heads/3 tails or 5 tails/3 heads? what is the probability of getting a 5 to 3 ratio either way?

I'd be glad if anyone could help here.

thanks and cheers  :)

oh, and maybe: what is the probability of getting a 4/4 ratio either way.

5 heads/3 tails: p= 0.218
5 tails/3 heads: p= 0.218
-----------------------------------------
Sum: p= 0.436

Whats your name at paroli ?
