In probability theory, the expected value (often noted as E(x)) refers to the expected average value of a random variable one would expect to find if one could repeat the random variable process a large number of time. In other words, the expected value is a weighted average of all possible values in the experiment.
In probability theory, a Bernoulli trial is a random binary experiment with the two outcomes being either "success/failure" or "yes/no". For it to be a Bernoulli trial the success and failure rate must be the same for each repeated experiment.
The calculation for this is very easy but understanding how a Bernoulli trial works is essential to understanding probability.
