The Mars candy company claims that 20% of all milk chocolate M&Ms are orange.

1. In a sample of 80 M&Ms -> the probability that more than 23% of them will be orange?

2. 20% M&Ms that are orange are not given, but instead attempted to estimate this parameter through a sample of 150 M&Ms, where 19% of them are orange.(95% confidence level.) -> the margin of error on our estimate of 19%?
