Hello all,

I'd like to calculate the probability of having a +5.00% EV after flat betting 5,000 hands while playing a -.45% player advantage game of double-deck blackjack. Is it less than 1%? Can someone please show the math (z-statistic, etc.)?

I used Norm's Outcome Calculator https://www.qfit.com/calcrisk.htm
to answer this question. But his calculator requires entering monetary parameters (such as bet size and desired financial outcome) and not just the above terms, and I am not sure I entered the correct numbers.

Again, using the above numbers:

When flat betting $10 for 5,000 hands (by the way, can "hands" be said to be exactly equivalent to "rounds?") and ending up with a player EV of +5.00% while playing a -.45% player advantage game of double-deck blackjack, does this mean the player ends up with $2,500 ($10 X 5,000 hands X 5.00%)?

If this is true, again, is the probability of this occuring less than 1%?
