Factor completely. x 3 + 6x 2 - 4x - 24
a.(x + 6)(x - 2)(x + 2)
b.(x + 2)(x - 6)(x + 2)
c.(x - 6)(x + 2)(x + 2)x^3 + 6x^2 - 4x - 24 = x^2(x + 6) - 4(x + 6) = (x + 6)(x^2 - 4) = (x + 6)(x + 2)(x - 2)

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.
