Determine if the random variable from the experiment follows a Binomial Distribution. A random sample of 150 adults is selected. Each person is asked if they have an American Express card. The number of adults with an American Express card in the sample is recorded. It is known that the percentage of adults with an American Express card is 28%. 1. There there are two mutually exclusive outcomes (success/failure). [ Select ] 2. Since a sample size of 150 is less than 5% of the total population of adults, the trials are independent. [ Select ] 3. There is a fixed number of trials. [ Select ] 4. The probability of success is the same for each trial of the experiment. [ Select ] The random variable follows a Binomial Distribution.
