In a wireless automatic meter reading system, a base station sends out a wake-up signal to nearby electric meters. On hearing th
e wake-up signal, a meter transmits a message indicating the electric usage. Each message is repeated eight times.
If a single transmission of a message is successful with probability p, what is the PMF of N, the number of successful message transmissions?

Answer: 0.475 cups of broth per serving.
Explanation:
1) Ratio given:
i) To facilitate the operations, transform the mixed number 4 3/4 cups into improper fraction:
4 + 3/4 = [16 + 3] / 4 = 19 / 4
ii) ratio broth: servings
2) Proportion with the unknown number of cups of broth per serving:
3) Solve for the unknown:
