What conditions for the binomial distribution, if any, fail to hold in the following situations?

(a) For each of a company's eight production facilities, record whether or not there was an accident in the past week. The largest facility has three times the number of production workers as the smallest facility.

(b) For each of three shifts, the number of units produced will be compared with the long-term average of 560 and it will be determined whether or not production exceeds 560 units. The second shift will know the result for the first shift before they start working, and the third shift will start with the knowledge of how the first two shifts performed.
