Assume that 28% of randomly selected adults have high cholesterol (with a level of at least 240mg/dl. or are taking medicine to reduce cholesterol). Based on results from the National Center for Health Statistics. Assume that a group of five adults is randomly selected. Find the probability that at least one of the adults has high cholesterol, does the result apply to five adults from the same family? why or why not?

Step 1

No of randomly selected = 5

Probability that a randomly selected adults have high cholesterol = 0.28

Probability that at least one of the adults has high cholesterol is given by

Applying Binomial theorem

Probability of x success out of n trial is given by
