You can calculate the probability of all hands with complete accuracy. Sometimes, if there are excessive tens and aces still in the shoe, they will have a positive expectation. But if you aren't keeping track of these cards, i.e. counting, you have no extra knowledge of the cards likely to be dealt, and therefore the expectation is exactly what it would be for the first hand.

If the first hand from a shoe, you can calculate the probability (win/loss) of that hand with complete accuracy. Many hands have a positive expectation even with skewed distribution of the deck. All this is beside the point; it is not necessary to know the next hand's expectation to determine your bet size.
All this streak stuff is total bunk. Give it a rest.
