You need to understand the basic statistical concept of Standard Deviation. The "probability of any event being below 4 (or X) standard deviations is the same for BJ as it is for anything else. I suggest that you learn what Z-Scores are.
EV is expected value, given a fixed set of conditions. Your actual results will be above or below EV, by perhaps as much as a few standard deviations, although more that 3 standard deviations away from EV is highly unlikely.
