Question: Breakfast sales at a small restaurant average $100 per day with a standard deviation of $15. A detailed look at the accounts shows that breakfast sales are between $85 and $115 for just over 68% of the days; more than 95% of days the sales are between $70 and $130; and very rarely do breakfast sales exceed $145 or fall below $55. The accounts show that days with sales lower than $100 are just as common as days with sales greater than $100.

What is the probability that breakfast sales will fall between $75 and $130 on any given day?
