The Expected value of a draw from the given question is; A; 0.77

We are told the face cards are K, Q, J. This means that there are 3 face cards for each of the 4 suits.

Since you earn 10 points for each face card, it means that;

total possible gain = 10 × 3 × 4 = 120

In a deck of cards, there are a total of 52 cards.

This means that;

Number of cards that are not K, Q or J = 52 - (4 × 3) = 40

Since 2 points are lost for drawing any of this 40 cards, then;

Total possible loss = 40 × 2 = 80

Expected gain = 120 - 80

Expected gain = 40

Expected value of a draw = 40/52

Expected value of a draw = 0.77

Why is hypotenuse always positive when dealing with Soh cah toa in graphs?
Akimi4 [234]
By definition <span>a2=b2+c2</span>, so if b<0 or c<0 or both, b2 and c2 will (always) be positive, and so their sum will always be positive, therefore the hypotenuse, a<span>, will always be positive.
