There are 3 face cards for each of the 4 suits, leading to a total possible gain of 120, there are 40 other cards leading to a total possible loss of 80.
120 - 80 = 40.
40 / 52 (total number of cards) = about .77

Final Answer:
The expected value of a draw is positive 0.77 points.
Hope I helped :)

Answer:

DG is 8.75.

Step-by-step explanation:

Because we have an isosceles triangle with a perpendicular bisector, we have two identical triangles which share equal sides. We know DF is 14 and FG is 4x. These are corresponding sides and we set them equal.

4x=14

x= 3.5.

We also know DE=EG and that DE=1.25x.

We substitute this term and x=3.5.

1.25x=EG

1.25(3.5)=EG

EG is 4.375.

We double 4.375 to find the whole segment DG since they are equal halves. DG is 8.75.
