Answer:
The problem is incomplete, but it is solved using a binomial distribution with and
Step-by-step explanation:
For each adult who regret getting tattoos, there are only two possible outcomes. Either they say that they were too young, or they do not say this. The answer of an adult is independent of other adults, which means that the binomial probability distribution is used 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.
16% say that they were too young when they got their tattoos.
This means that
Eight adults who regret getting tattoos are randomly selected
This means that
Find the indicated probability.
The binomial distribution is used, with , that is:
