Among 21 - to 25-year-olds, 29% say they have driven while under the influence of alcohol. Suppose that three 21 - to 25-year-olds are selected at random. a) What is the probability that all three have driven while under the influence of alcohol

P (3) = 0.0244

P (3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Step-by-step explanation:

Given;

The probability that they have driven while under the influence of alcohol is;

P = 29% = 0.29

the probability that all three selected have driven while under the influence of alcohol is;

P (3) = P * P * P

P (3) = 0.29 * 0.29 * 0.29

P (3) = 0.024389

P (3) = 0.0244

P (3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244
