Aliza needs to run at a rate faster than 8.2 feet per second in order to exceed her fastest time in a race. After
running for 15 minutes, her coach determines that she is
running at an average rate of 5.8 miles per hour. He
converts the average rate to feet per second as shown
below:

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?
