The amounts a soft drink machine is designed to dispense for each drink are normally distributed, with a mean of 12.4fluid ounces and a standard deviation of 0.3fluid ounce. A drink is randomly selected.(a) Find the probability that the drink is less than 12.2fluid ounces.(b) Find the probability that the drink is between 12and 12.2fluid ounces.(c) Find the probability that the drink is more than 12.9fluid ounces. Can this be considered an unusual event? Explain your reasoning
