Answer:
13.44% probabilith that at most 3 are in excellent health.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they are in excellent health, or they are not. The probability of an adult being in excellent health is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
43% of adults questioned reported that their health was excellent.
This means that
13 adults randomly selected
This means that
Find the probability that when 13 adults are randomly selected, at most 3 are in excellent health.
In which:
13.44% probabilith that at most 3 are in excellent health.
