2. In a recent poll, 81% of parents with children under 18 years of age said that it is more difficult to raise children now. Assume that this percentage is true for the current population of all parents with children under 18 years of age. You take a random sample of 1000 such parents. Using the binomial probability formula: a) Find the probability that from within the sample 800 or less will hold the same view. b) Find the probability that from within the sample, 800 to 830 will hold the same view.
