Experimental Probability

What is Experimental Probability -Tells us the probability of a performed experiment The desired outcome All possible outcomes

Example: The spinner was spun 10 times and the results were as follows: Blue was spun 3 times Yellow was spun 5 times Red was spun 2 times What is the experimental probability for each color? Blue: (3/10) Yellow: (5/10) Red: (2/10)

Writing probability as decimals and percents Use previous knowledge and convert the fraction to a decimal using proportions. Blue: 3_ = _x 10 100 =30% OR .3 Yellow: 5 = x 10 100 =50% OR .5 Red: 2 = x =20% OR .2

Marshmallow Toss Experiment Toss each marshmallow 50 times in your groups Solve for the experimental probabilities and complete the rest of the worksheet on your own. Create a graph on your laptop of the data. Prepare to share your results

Were all of the results the same? Why do you think the experimental probability was different for each group? Was there a difference between the marshmallows? Why do you think this is? If you were using a large marshmallow in a coin flip what side would you choose? Why? What about a small marshmallow?
