You have one suit of a standard deck of playing cards and you use their denominations as the vertex names in a rooted tree. The Ace is the designated vertex, the root of the tree. The Jack, Queen, and King are children of the Ace. The prime number cards are children of the King; the even number cards that are not prime are children of the Queen, and the odd number cards that are not prime are children of the Jack. For all three questions answer with a fraction, for example, 1/2 is a fraction. If you randomly pick a leaf from the tree, what is the probability that you picked a child of the Jack or the King

Given: ∆mop p∆mop =12+4 3 m∠p = 90°, m∠m = 60° find: mp, mo

Do you mind if you guys me with this question i’m on number 8

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?
