Answer:15
Explanation:Since these are similar triangles it means each contrasting side length has a ratio and the ratio for the side lengths is 1:3 based on 4:12 so you would multiple the side length of Db times 3 to find Ed and your answer is 15

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.
