suppose you remove the jacks, queens and kings from the deck. this leaves you with 40 cards, if the value of the remaining cards is equal to the face value ( the Ace being a value of 1), what is expected value of the remaining cards??????
Answers
Answer:
220
Step-by-step explanation:
A to 10 = 1+2+3+4+5+6+7+8+9+10 = 55
There are 4 suits,
4(1+2+3+4+5+6+7+8+9+10) = 4(55)
= 220
Given : jacks, queens and kings removed from the deck leaving 40 cards . considering Ace is being value of 1 .
To find : expected value of the 40 cards
Solution:
After removal of jacks, queens and kings from the deck.
remaining cards are 1 to 10 ( 4 Each) ( calling Ace as 1 )
Total Cards = 40
Probability of Each Cars = 4/40 = 1/10
Expected Value = ∑ ( probability * Value )
= (1/10) * 1 + (1/10)*2 + ............................................+(1/10)*9 + (1/10)*10
= (1/10) ( 1 + 2 + 3 + ...........................+ 9 + 10)
= (1/10) 10* 11/2
= 11/2
= 5.5
expected value of the remaining cards = 5.5
or Simply
Sum of all Card / ( number of Card)
= 4(1 + 2 + ............+ 9 + 10)/ 40
= 5.5
