## Main Question or Discussion Point

hi, i posted this question in the probability forum here but noone is even browsing that one.

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.
