The weights of chocolate chip cookies are normally distributed (bell-shaped) with an average weight of 12 ounces and a standard deviation of 0.25 ounces
1) If a bag of chocolate chip cookies is chosen at random, what is the probability that it will weigh more than 12 ounces?
2) If a bag of chocolate chip cookies is chosen at random, what is the probability it will weight between 11.5 and 12.5 ounces?
3)If a bag of chocolate chip cookies is chosen at random, what is the probability that it will weigh more than 11.75 ounces?
4) If a bag of chocolate chip cookies is chosen at random, what is the probability it will weight between 11.25 and 12.75 ounces?
5) If a bag of chocolate chip cookies is chosen at random, what is the probability that it will weigh more than 12.5 ounces but less than 12.75 ounces?
