Can you finish it?

Like this:

Probability of exactly one six:        p1 = (1/6)*(5/6)^2*3

Probability of exactly two sixes:   p2 = (1/6)^2*(5/6)*3

Probwbility of exactly three sixes:  p3 = (1/6)^3

Expected number of sixes:  1*p1 + 2*p2 + 3*p3

As follows:

Like so:

8wings*cost_of_wing + cost_of_gatorade = $15.99

cost_of_wing = ($15.99 - cost_of_gatorade)/8

You can crunch the numbers.

Like so:

As follows:

As follows:

(As an example consider N = 14).

Oops! My mistake.  c = 4 not 8, so y = -(1/2)x + 4

Make sure you check the details, don't just look at the answer!
