Assume you are working with a standard deck of 52 cards. there are 13 cards (2, 3,
4, 5, 6, 7, 8, 9, 10, jack, queen, king, and ace) in each of four suits (clubs, diamonds,
hearts, and spades).
what is p(9 u queen) if you draw one card?
1) 0
2) 2/13
3) 7/52
4) 4/13

Write the pair of fractions as a pair of fractions with a common denominator

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?

Using inductive reasoning, what are the next two number in this set? 2,3/2,4/3,5/4,
