A new type of soft drink from Frackly Inc. is sold in 500 milliliter (ml) bottles. The mean volume of drink placed in a bottle is 490 ml with a standard deviation of 6.1 ml. Assuming a normal distribution of the data, what is the probability that the filling machine will cause an overflow in a bottle, that is, the probability that more than 500 ml will be placed in the bottle? Please show work.
