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, 219 of the first 264 customers have not received a star on their receipt. What is the experimental probability of winning a free gallon of milk?options: 3/11....15/88....73/88.....1/78

Solution:

Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood, and each repetition is known as a trial.


\begin{gathered} P(E)=(n(E))/(n(T)) \\ \\ Where; \\ n(E)=\text{ number of event} \\ \\ n(T)=\text{ total outcome} \end{gathered}

If 219 of the first 264 customers have not received a star on the receipt, then a customer that would win a free gallon of milk would be among (264 - 219) customers. Thus;

The experimental probability of winning a free gallon of milk is;


\begin{gathered} =(264-219)/(264) \\ \\ =(45)/(264) \\ \\ =(15)/(88) \end{gathered}

CORRECT OPTION:


(15)/(88)
