Will give brainiest if you get it ! is the following definition of supplementary reversible. if yes, write it as a true biconditional. supplementary angles are two angles whose measures sum to 180 a)yes, if angles are supplementary, then their measures sum to 180 b)yes, angles are supplementary if (and only if) their measures sum to 180 c)yes, angles are supplementary if their measures sum to 180 d)the statement is not reversible

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?
