  1. Warm-up5.1 Fundamentals of Probability A botanist is interested in determining the effects of scheduled watering. Twenty identical plants were paired and placed in the same location of a green house. Of the pair, one was randomly picked for scheduled watering. The other plant received the same amount of water over a week but it was at random times of the day. The botanist compared the growth of each of the pairs of plants after 6 weeks. • What type of experimental study is this? • What is the treatment? • What are the experimental units? • What is the response variable?

  10. 5.1 Introduction to Probability

  11. Probability Distribution Suppose we want to list the sample space of the result of flipping two coins. If we include the probabilities it is considered a probability distribution. The complement of any event is 1 – P(event). What is the probability of not getting TT or what P( TTc )?

  12. Multiplication Counting Principal The two spinners are mutually exclusive (independent events). Multiplication (Counting) Principal states that by multiplying the possible outcomes in each category, we can find the total number of possible arrangements.

  13. Law of Large Numbers Let’s say you suspect your friend has unfair die. How would you actually find out if the die is weighted unequally?
