The probability that at least one of the four Indiana adults selected is a gun owner is approximately 0.52.
To find the probability that at least one of the four Indiana adults selected is a gun owner, you can use the complementary probability principle, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.
In this case, the probability that none of the four Indiana adults selected is a gun owner is [tex](1 - 0.338)^4 = 0.48[/tex] Therefore, the probability that at least one of the four Indiana adults selected is a gun owner is 1 - 0.48 = 0.52.
Therefore, the probability that at least one of the four Indiana adults selected is a gun owner is approximately 0.52.
