Expected Values - chrislduan/Blackjack GitHub Wiki

With a starting deck, there are 52 cards We will assign all face cards with a value of 10 At the start we will assign Aces with value of 1

E(X) = 12/52 * 10 + 1/1310 + 1/139 + 1/138 + 1/137 + 1/136 + 1/135 + 1/134 + 1/133 + 1/132 + 1/131 = 6.53 Var(X) = 12/52*(10-6.53)^2 +

Generally, a starting hand will have an expected value of around 13 as it starts with 2 cards. Of course we are assuming that after the first card is pulled the expectation doesn't change as much.
