2. Find the domain and range of the function shown in the graph. Write the domain and range using interval notation.
A domain: (-3,2)(3,7)
range: (-6,-1) (1,5)
B domain: (-6,-1] U(1,5]
range: (-3,2][3,7)
C domain: (-3,2][3,7)
range: (-6,-1] (1,5)
D domain: (-6,-1) (1,5)
range: [-3,2)(3,7)

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?
