Based on a poll, among adults who regret getting tattoos, 23% say that they were too young when they got their tattoos. Assume that ten 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.
b. Find the probability that exactly one of the selected adults says that he or she was too young to get tattoos.
c. Find the probability that the number of selected adults saying they were too young is 0 or 1.
d. If we randomly select ten adults, is 1 a significantly low number who say that they were too young to get tattoos?
▼No, Yes,
because the probability that
▼at least 1, more than 1, exactly 1, less than 1, at most 1
of the selected adults say that they were too young is
▼greater than less than or equal to
0.05.
