As you all know, the end of the school year is just around the corner. We want to prepare you for the best success and ending the year strong. Remember to continue to attend tutoring sessions, after school homework clubs, and looking forward to having a productive summer. VOLUNTEER this summer and read in preparation for your sophomore year.
LET’S GET IT!
Experimental probability is the likelihood that an event will occur based on the outcomes on previous results.
Sample space is the total number of outcomes of an event
There is a general method that you following when discovering the fundamental counting principle (FCP).
ex. 4 hoagies: 3 types of meat, four types of cheeses
How many different combinations can you make ?
MEAT: turkey, ham, liverwurst CHEESE: provolone, cheddar, American, swiss
First method: match each meat with each type of cheese using a tree diagram
Second method: multiply the total # of meats by the total # of cheeses
FCP = 3 (# of meats) x 4 (# of cheeses) = 12 combinations

Students,
Benchmarks are quickly approaching. All of the lessons and materials that you will receive in class this week will be related to the problems that will be presented on the Benchmarks.
Let’s review…
PROBABILITY
Probability is the chance that an event or circumstance will take place. There are two types of probability: theoretical and experimental probability.
Theoretical: the likelihood that an event will occur based on number of possible outcomes
Experimental: the likelihood that an event will occur based on the outcomes on previous results
Points to remember
Students,
Benchmarks are quickly approaching. All of the lessons and materials that you will receive in class this week will be related to the problems that will be presented on the Benchmarks.
Let’s review…
FACTOR TRINOMIALS
The standard form for trinomials has three terms: ax^2 + bx + c, where A = 1st term, B = 2nd term, and C = 3rd term. Using the “X” method, we place our B value on the top and our C value on the bottom.
B value: sum of side numbers C value: product of side numbers
Points to remember
Three very important vocabulary terms that you should remember.
Trial- the number of events that occur
Favorable outcome- a desired result based on prediction
Experimental outcome- the result received after a trial
Two formulas to remember: Theoretical probability and Experimental probability
Theoretical probability: the predicted probability of an event
Experimental probability: the run of trials
Theoretical probability- P(event) = # of favorable outcomes/# possible outcomes
Experimental probability- P(event) = # of favorable outcomes/# trials
Examples
What is the probability of flipping a coin?
Theoretical: 1/2 (there are two sides and each side is represented by the number one)
Experimental: ?/2 (there are different outcomes and two sides of a coin)
