Concept #1: Determining the Probability of an Observation

Concept #2: Determining the Probability of an Observation: Intro

Practice: The United States is said to be one of the nations that consumes the most calories (per person). The average caloric intake for each individual within the U.S. is said to be 2,700 with a standard deviation of 250. What is the probability that you randomly select an individual and they consume more than 3,150 calories?

Practice: The daily recommended caloric intake is 2,000 calories. Referring to Practice 1, what is the probability that you randomly select an American who consumes more than the daily recommended amount of calories?

Practice: Bacardi 151 is a type of liquor that is flammable so it is often used in shots that are set on fire. The average and variance for the alcohol content in any given bottle is 75.5% and 2.5%, respectively. What is the probability that you randomly purchase a bottle with alcohol content between 74.65 and 79.05%?

Practice: You tend to black out if you consume alcohol with higher than 70% alcohol content by volume. Referring to Practice 3, what is the probability that you black out from drinking a randomly selected bottle of Bacardi 151?
