A jar contains 4 cherry cough drops and 10 honey cough drops. You choose one cough drop at random without looking. The cough drop is cherry. Find the probability of that event. Write it as a fraction in simplest form, a decimal, and a percent to receive full credit!
4/14 = 2/7 = 0.286 = 28.6% or you could have rounded to 29%

What is the probability of a tail when a fair coin is tossed? To receive full credit write your fraction in simplest form, and give the equivalent decimal and percent.
1/2 = 0.5 = 50%

The theoretical probability of a given event is 9/13. Explain what each number represents?
9 represents the ways the events can occur; 13 represents the number of equally likely outcomes.

Mrs. Hernandez is ordering a taco. She can order a corn tortilla or a flour tortilla. She can choose beef, fish, chicken, or zucchini as the filling. She can also choose sour cream or guacamole. Each combination is equally likely. Find the probability that a taco she chooses at random has a corn tortilla, fish, and guacamole.

What is the difference between theoretical probability and experimental probability?
Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.
