Below is another student's solution to a normal approximation problem. Identify each step with an error compared to the previous steps, and explain why it is an error Problem: In a game, 1 in 5 treasure chests contains a rare item. Calculate the probability that you find 8 rare items in a collection of 50 treasure chests, using the normal approximation to the binomial distribution. Solution:
