Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
The probability of 
successes in 
trials where 
is the probability of success on any given trial is given by:
\ =\ \left(n\cr k\right\)\left(p\right)^k\left(1\,-\,p\right)^{n\,-\,k})
Where )
is the number of combinations of things taken at a time and is calculated by !})
So:
\ =\ \left(3\cr 3\right\)\left(0.5\right)^3\left(0.5\right)^{0})
You can do your own arithmetic.
Hint: \ =\ 1\ \forall\ n\ \geq\ 0\ \in\ \mathbb{Z})
