Use the following information to answer the next 3 parts.

A new medication being tested to minimize the symptoms of celiac disease has been shown to have several side effects which may affect a patient's decision to use it. The following table gives estimated probabilities of side effects of this medication.

Side EffectsProbability Probability of Occurrence

Hypertension. 0.01

Heartburn 0.06

Diarrhea 0.06

Muscle Fatigue 0.15

Other?

None 0.63

Part 1: One of the values is missing from the table. What should that missing probability be, if the table is supposed to be a probability distribution?

Part 2: Randomly select a patient that takes this medication. According to the table, what is the probability that the patient experiences heart burn or muscle fatigue?

Part 3: Again, randomly select a patient that takes this medication. According to the table, what is the probability that the patient does not experience diarrhea as a side effect?

Give all your probability answers as decimals, such as 0.123.
