What Apgar scores are typical? To find out, researchers recorded the Apgar scores of more than 2 million newborn babies in a single year. Imagine selecting one of these newborns at random. (That’s our chance process.) Define the random variable X = Apgar score of a randomly selected newborn baby. The table gives the probability distribution of X.
Using the table find P(X = 3) = ?
