It has been observed in a city that 64% of the people who go to cinema at weekend are women. In a weekend 80 people who go to cinema are chosen randomly. a. Show that we can use normal distribution to determine probabilities. b. What is the probability that less than 63% of the people in this group are women? c. What is the probability that more than 75% of the people in this group are women?
