We use the binomial probability formula,
:
Probabilty(P) (k events out of n occurances) = nCk * p^k * (1-p)^(n-k), where p is the probability of one event and nCk is the combination of n trials taken k at a time
:
We are given n=8, p=0.75
:
P ( k > 6 ) = P ( k = 7 ) + P ( k = 8 ) = 0.266 + 0.100 = 0.366 approximately 0.37
