Hasaan has a spinner with 5 equal sections, each a different color. After only 10 spins, the pointer had landed on red 40% of the time. After a whopping 1,000 spins, the pointer landed on red only 22% of the time. How can Hasaan account for this change in experimental probability?
As the number of trials increase, the experimental probability reaches closer to the theoretical probability.
You are trying to decide what to wear to school. You know you have a green pair of pants, a red pair, and a blue pair. You also have a brown shirt, a plaid shirt, and a yellow shirt. How many different outfit combinations can you make?

Define "outcome"
a possible result of an experiment
Joey flipped a coin 20 times. It landed on heads 12 times. Based on the experiment, what's the probability that it will land on heads on the next flip?
3/5, 0.6, or 60%
Define "sample space"
the set of all possible outcomes
A letter tile is randomly selected from a bag, recorded, and replaced 100 times. The results are listed below. What is the experimental probability of selecting the letter "E"? A = 16 E = 11 I = 29 O = 19 U = 25
11/100 or 0.11, or 11%
Describe the difference between events that are certain, likely, equally likely, unlikely, or never going to happen.
Certain would be 100% of the time, likely is anything greater than 50% of the time, equally likely is exactly 50% of the time, unlikely is anything less than 50% of the time, and never is anything that has a 0% chance of occuring.
Pedro recorded the types of birds that visit his bird feeder. Based on the results below, what is the probability the next bird will be a chickadee? Woodpecker = 3 Chickadee = 5 Cardinal = 1 Sparrow = 13 Blue Jay = 3
1/5, or 0.20, or 20%
Define "theoretical probability"
the probability of what should happen in an experiment
A six-sided die is thrown 50 times. Using the list below, how does the theoretical probability of rolling a 3 compare to the experimental probability of rolling a 3? (Number on Die: How Many Times it Landed on that Number) 1: 8 times 2: 6 times 3: 7 times 4: 12 times 5: 10 times 6: 7 times
The theoretical probability is higher than the experimental probability. (Theoretical = 17%, Experimental = 14%)
Define "experimental probability"
the probability of what actually happens after an experiment
