Hey All,

This is a pretty simple one but i just want to make sure.

5 people flip a coin... what is the probability that there will be one odd-man out (i.e. 4 heads, 1 tail; 4 tails, 1 head).

Isn't it 1/32 ?

Paul is correct -

To get 4 haeds and 1 tail -

(1/2) * (1/2) * (1/2) * (1/2) * (1/2) * 5 = 5/32

Same way, to get 4 tails and 1 head -

5/32

So,

probability = 5/32 + 5/32 = 5/16

cheers,

Dharmin
