If you flip a coin 10 times, about how many times should it land on heads?
A letter tile is randomly selected from a bag, recorded, and replaced 105 times. The results are listed below. What is the experimental probability of selecting the letter "E" or "O"? A = 16 E = 11 I = 29 O = 19 U = 25
(11+19)/105 = 0.2857 = 28.6%
How likely is it that a number cube is tossed and it lands on 8?
impossible
Describe the difference between events that are certain, likely, unlikely, or impossible.
Certain would be 100% of the time, likely is anything greater than 50% of the time, unlikely is anything less than 50% of the time, and impossible is anything that has a 0% chance of occuring.
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. (The Law of Large Numbers)
