Question 1166562: The fill weight of a certain brand of adult cereal is normally distributed with a mean of 910 grams and a standard deviation of 5 grams. If we select one box of cereal at random from this population, what is the probability that it will weigh less than 904 grams?
**I understand what the question is asking, it's been so long since I've done this I need a refresher on the formulas and steps. I do know the answer is .1151
Thanks

z=(x-mean)/sd
z<(904-910)/5
z<= -6/5
probability is 0.1151
