Therese manages a grocery warehouse that encourages volume shopping on the part of its customers. Therese has discovered that on any given weekday, 95% of the customer sales amount to more than $100. That is, any given sale on such a day has a probability of 0.95 of being for more than $100. (Actually, the conditional probabilities throughout the day would change slightly, depending on earlier sales, but this effect would be negligible for the first several sales of the day, so we can treat them as independent.) Find the probability of the following event. Exactly one of the first three sales on Wednesday is for more than $100.

Oh gosh i love these questions. so, to find the proportion/unit rate, we do 12 shoelaces over 3 minutes i believe. we need to find x over y as our unit rate basically. so, write s (shoelaces) over m (minutes) a divide sign and then x (unit rate for shoelaces) over y (unit rate for minutes). i hope this is correct, else just look online for unit rate !
