**b) Determine the probability of observing 76 or fewer successes.**
\[ P(\text{Observing 76 or fewer successes}) = \_\_\_\_ \]
*(Round to four decimal places as needed.)*
---
**c) Determine the probability of observing 66 or more successes.**
*(Continue with the calculation in the same manner, ensuring use of cumulative standardized normal distribution tables as necessary.)*
