The probability of k successes in n independent trials where p is the probability of success on any given trial is given by:
\ =\ {{n}\choose{k}}(p)^k(1-p)^{n-k})
Where 
is the number of combinations of n things taken k at a time.
So you want \ =\ {{11}\choose{10}}(0.95)^{10}(1-0.95)^{11-10})
Hint: If you are unfamiliar with the notation, the value can be calculated by !)
