Answer: The answer is D
Step-by-step explanation:
The expected value of the number of points for each turn is 0.25
<h3>What is expected value?</h3>
Expected value describes the long term average level of a random variable based on its probabilty distribution.
Now, Probability that 2 heads come up is
P(2 is H) = 1/4
Probability that 1 heads come up is
P(1 is H) = 2/4
⇒P(1 is H) = 1/2
Probability that no head will come up
P(no H's) = 1/4
Hence, the expected value for winning of 2points, 1point and lose of3 points is given as-
Expected value = 2 * P(2 is H) + 1 * P(1 is H) - 3 * P(no H's)
⇒Expected value = 2 * 1/4 + 1 * 1/2 - 3 * 1/4
= 0.5 + 0.5 - 0.75
⇒Expected value = 0.25

Answer:
SAS
Step-by-step explanation:
In triangle ABC and triangle EFD
1. BC = CD (S) Given
2. < BCD = < EFD (A) being vertically opposite. angles.
3. AC = CE (S) Given
Hence
By SAS postulate Triangle ABC and triangle EFD are congruent.
