Try the binomial distribution.
Here is the formula:
P(x) = (nCx)(p^x)[q^(n-x)]
x = 0
p = .05
n = 23
Substitute into the formula to determine the probability.
the probability that a house in an urban area will develop a leak is 5%. if 23 houses are randomly selected, what is the probability that none of the houses will develop a leak?
