A theater was designed with 15 seats in the first row, 19 in the second row, 23 in the third row, and so on. Write a function that represents this seating pattern to determine how many seats are in any row.
a(n) = 15 + 4(n)
O a(n) = 15 + 4(n-1)
an) = 23 + 4(n)
an) = 23 + 4(n-1)

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.
