Marsha completed an experiment using a spinner cut into equal sized spaces. The spinner had 3 yellow, 3, red, 3, blue, 1 green, and 2 pink spaces on it. The table below shows the results of her spinning experiment where she tallied the result of each spin completed. Which color's theoretical probability matched it's experimental probability? Which color's experimental probability was highest?

Atemperature of 1.64◦f corresponds to answer in units of ◦c.

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?
