\ =\ \sum_{i=0}^k\left(n\cr i\right\)p^i\left(1\,-\,p\right)^{n\,-\,i})
Where )
is the number of combinations of 
things taken 
at a time and is calculated by !})
Just substitute the given values:
\ =\ \sum_{i=0}^k\left(3\cr i\right\)\left(\frac{1}{4}\right)^i\left(\frac{3}{4}\right)^{3\,-\,i}\ \forall\ k\ \in\ \{0, 1, 2, 3\})
