Considering the probability of success of 0.8 in the Bernoulli trial, the probability of failure is of 0.2.
The probability of failure in a Bernoulli trial is one subtracted by the probability of a success.
In this problem, the probability of a success is of 0.8, hence the probability of failure is:
pF = 1 - 0.8 = 0.2.
