Quizplus · Accepted Answer

The probability of exactly 5 students having a tattoo can be calculated using the binomial probability formula: P(X = k) = C(n, k) * p^k * (1-p)^(n-k), where n = 15, k = 5, p = 0.30, and C(n, k) is the combination of n items taken k at a time. Plugging these values into the formula gives a probability of approximately 0.2069, which rounds to 0.207.
