Use the appropriate normal distribution to approximate the resulting binomial distribution.
An experiment was conducted to test the effectiveness of a new drug in treating a certain disease. The drug was administered to 50 mice that had been previously exposed to the disease. It was found that 30 mice subsequently recovered from the disease. It was determined that the natural recovery rate from the disease is 0.5. Determine the probability that 30 or more of the mice not treated with the drug would recover from the disease.
a. The probability is 0.0975.
b. The probability is 0.1020.
c. The probability is 0.1160.
d. The probability is 0.6840.
b. The probability is 0.1020.
