In a health examination survey of a prefecture in Japan, the population was found to have an average fasting blood glucose level of 99.0 with a standard deviation of 12. Determine the probability that an individual selected at random will have a blood sugar reading:

a. Greater than 120 (let the random variable for this be denoted as X; then we can write the probability of this event as P(X > 120)

b. Between 70 and 100, P(70 < X < 100)

c. Less than 83, P(X < 83)

d. Less than 70 or greater than 110, P(X > 110) + P(X < 70)

e. That deviates by more than 2 standard deviations (24 units) from the mean
