Food Express is running a special promotion in which customers can win a free gallon of milk with their food purchase if there is a star on their receipt. So far, 171 of the first 187 customers have not received a star on their receipts. What is the experimental probability of winning a free gallon of milk? I have been stuck on this question ever since it was assigned! It makes no sense! Please help!

Question

kiwibyrd · Answer

first, set up an equation. number of customers who have not received stars / total customers

livielaughs · Answer

ok and in total there is 358

kiwibyrd · Answer

no no, there are 187 in total.

kiwibyrd · Answer

171/187 should be your fraction

livielaughs · Answer

oh.

kiwibyrd · Answer

then, take the denominator (187) and subtract the numerator to find the number of people who DID get a star

kiwibyrd · Answer

take that number, put it over the total number of customers (187) and reduce, and thats your answer

livielaughs · Answer

ok so the overall answer is 16/187 because you cant reduce it right?
