The probability of the player making his next 3 free throws (P(W)) is:

The probability of the player NOT making his next 3 free throws (P(L)) is:

Expected value (EV) is given by the payoff of each outcome multiplied by its probability:

The expected value of the proposition is -$0.90
Answer:
$0.75 per song
Step-by-step explanation:
Given that the relationship between variable s and c is a proportional relationship, and is represented by the equation, c = 0.75s.
Where,
c = total costs
s = number of songs
The constant of proportionality, k, = 0.75.
Thus, 0.75 represents the cost per sing downloaded.
The answer is:
