Based on a poll, among adults who regret getting tattoos, 27% say that they were too young when they got their tattoos. Assume that seven adults who regret getting tattoos are randomly selected, and find the indicated probability. Complete parts (a) through (d) below. a. Find the probability that none of the selected adults say that they were too young to get tattoos. (Round to four decimal places as needed.) b. Find the probability that exactly one of the selected adults says that he or she was too young to get tattoos. (Round to four decimal places as needed.) c. Find the probability that the number of selected adults saying they were too young is 0 or 1. (Round to four decimal places as needed.) d. If we randomly select seven adults, is 1 a significantly low number who say that they were too young to get tattoos? v because the probability that v of the selected adults say that they were too young is v0.05.

**Problem: Evaluating Probabilities Based on a Poll about Tattoo Regrets**

Based on a poll, among adults who regret getting tattoos, 27% say that they were too young when they got their tattoos. Assume that seven adults who regret getting tattoos are randomly selected, and find the indicated probability. Complete parts (a) through (d) below.

**a. Find the probability that none of the selected adults say that they were too young to get tattoos.**

\[ \text{Probability:} \quad \_\_\_\_\_ \quad (\text{Round to four decimal places as needed.}) \]

**b. Find the probability that exactly one of the selected adults says that he or she was too young to get tattoos.**

\[ \text{Probability:} \quad \_\_\_\_\_ \quad (\text{Round to four decimal places as needed.}) \]

**c. Find the probability that the number of selected adults saying they were too young is 0 or 1.**

\[ \text{Probability:} \quad \_\_\_\_\_ \quad (\text{Round to four decimal places as needed.}) \]

**d. If we randomly select seven adults, is 1 a significantly low number who say that they were too young to get tattoos?**

\[ \text{Select the correct answer:} \quad \_\_\_\_\_ \quad \text{because the probability that} \quad \_\_\_\_\_ \quad \text{of the selected adults say that they were too young is} \quad \_\_\_\_\_ \quad \text{0.05.} \]

---

This problem involves calculating probabilities for different scenarios using a binomial distribution, given that 27% of adults who regret getting tattoos say that they were too young when they got their tattoos. The questions require rounding answers to four decimal places where applicable. Consider using binomial probability formulas or tables to determine the specific probabilities needed for each part.
