A survey of 13 California residents was conducted to determine how many have adequate earthquake supplies. It is estimated that only 30% of California residents are prepared. The number who are prepared is a random variable X that can take on the values of 0, 1, 2, ..., 13. The expected value of X is 3.9 residents, which is rounded to the nearest whole number of 4 residents expected to be prepared.
