hi, i posted this question in the probability forum here but noone is even browsing that one.(adsbygoogle = window.adsbygoogle || []).push({});

my brother needs to know this but i'm in exam block right now and can only think of the physics im studying this term. i cant remember how to figure this out anymore i just know i'll probably have to use nCr and nPr.

heres the question:

how do i find the probability of getting tossing 3 heads in a row out of 64 tosses?

thanks, much appreciated.
