The probability that house sales will increase in the next 6 months is estimated to be 0.25. the probability that the interest rates on housing loans will go up in the same period is estimated to be 0.74. the probability that house sales or interest rates will go up during the next 6 months is estimated to be 0.89. find the probability that house sales will increase but interest rates will not during the next 6 months.

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?
