Building a probability distribution, it is found that the expected value for both players is of 0.25 points.
- The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the four possible outcomes, considering Player A - Player B, are:
H - H
T - H
H - T
T - T
That is, considering a success as the number of heads, the distribution is:
For Player A, the earnings of each outcome are: -1, 0 and 2
Hence, the expected value is:
For Player B, the earning of each outcome are: 2, 0 and -1.
Hence:
The expected value for both players is of 0.25 points.

Answer:
arc TSR = 180°
arc US = 110°
arc RU =130°
∠RPQ = 60°
arc QRT = 240°
arc UTQ = 290°
Step-by-step explanation:
arc TSR = 180° because half circle
arc US = 110° because 50° + 60°
arc RU =130° because 180° + 50°
∠RPQ = 60° because vertical to 60°
arc QRT = 240° because 180° + 60°
arc UTQ = 290° because 360° - 70°
