(1 point) Suppose that 43% of households in a city have children. You take a random sample of 20 households from the city. Let x represent the number of households in your sample that have children. Find the following probabilities. (a) P(x = 4 or 12) (b) P(x <10) (c) P(x > 7) = (d) P(x < 12) = = (e) P(x >10) = = =

If a binomial experiment has probability p success, then the probability of failure is ____________________. The probability of getting exactly r successes in n trials of this experiment is C(_________, _________)p (1p)

(a) An experiment has two outcomes, "success" and "failure„" where the probability of success" is p. The experiment is performed n times. What of probability is with this experiment? (b) What is the probability that success occurs exactly r times? (c) An archer has probability 0.6 Of hitting the target. find the probability that she hits the target exactly 3 times in 5 attempts-
