A recent study suggested that 75% of all meals marketed specifically to babies and toddlers and sold in grocery stores had high sodium content.51 This is of deep concern because increased salt in the diet can cause hypertension, which may lead to cardiovascular disease. Suppose 30 toddler meals are randomly selected and the sodium content in each is carefully measured.

a. What is the probability that exactly 23 meals will have high sodium content?

b. What is the probability that at least 25 will have high sodium content?

c. Suppose at most 20 meals have high sodium content. What is the probability that at most 15 will have high sodium content?
