1. Identify the parameters of the binomial distribution:
n = 16, \, p = 0.5, \, \text{and we need } P(X \leq 12)
2. Write the cumulative probability formula for the binomial distribution:
P(X \leq 12) = \sum_{k=0}^{12} \binom{16}{k} (0.5)^k (0.5)^{16-k}
3. Simplify the general term:
(0.5)^k \cdot (0.5)^{16-k} = (0.5)^{16}
4. Calculate the cumulative sum:
P(X \leq 12) = \sum_{k=0}^{12} \binom{16}{k} (0.5)^{16}
Using technology or tables:
P(X \leq 12) \approx 0.9717
Answer: The probability that no more than 12 of the entry forms will include an order is approximately 0.9717.
