Answer:
the probability that none of the selected adults say they were too young to get tattoos is approximately 0.4103 or 41.03%.
Explanation:
To find the probability that none of the selected adults say they were too young to get tattoos, we need to calculate the complement of the given probability.
Given:
- Among adults who regret getting tattoos, 17% say they were too young.
To find the probability that none of the selected adults say they were too young, we subtract the probability that at least one adult says they were too young from 1 (since the sum of all probabilities must equal 1).
Let's calculate it step by step:
Probability that an adult says they were too young = 17% = 0.17
Probability that an adult does not say they were too young = 1 - 0.17 = 0.83
Since the adults are randomly selected and the events are independent, we can multiply the probabilities together to find the probability that none of the selected adults say they were too young.
Probability that none of the selected adults say they were too young = (0.83)^4 ≈ 0.4103
Therefore, the probability that none of the selected adults say they were too young to get tattoos is approximately 0.4103 or 41.03%.
