      If the expected proportion is more than half, then plan the sample size based on the proportion expected NOT to have the characteristic. That is, switch the roles of P and 1-P. If P or 1-P is very close to 0 or 1 (i.e. the characteristic of interest is rare or happens most of the time), the sample size formula of N = 1 / E2 is not appropriate.
