Kelly uses point p to represent the sum of 3.6 + (-2.4) on the number line. 3.6+(-2.4) =P
Kelly says that point p is plotted to the right of both 3.6 and -24 on the number line because addition means you should move right on the
number line.
• Explain why Kelly's reasoning is incorrect.
• Explain how the location of p on the number line is related to the locations of 3.6 and -2.4 on the number line,
• Determine the value of point p.

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
