Layla flipped a coin 10 times and landed on heads 4 times. What is the experimental probability of landing on heads?
2/5, 0.4, or 40%.
Define "probability."
The likelihood or chance that an event will occur.
The classic wood carousel at Carousel Park in Hampton, VA has 32 jumping horses and 16 standing horses. What is the probability of randomly selecting a jumping horse?
2/3, or 0.67, or 67%
Jason rolled a die 20 times. He landed on 2 five times, 3 seven times, 6 two times, and 5 six times. What is the experimental probability of landing on 6?
1/10, 0.1, or 10%
Define "theoretical probability."
It is the probability of what should occur.
Define "experimental probability."
The probability of what actually occurs.
There are 3 red marbles, 2 green marbles, and 1 yellow marble in a box. One marble is taken out and replaced. A second marble is then taken out and replaced. What is the probability both marbles that were taken out are red?
1/4, or 0.25, or 25%
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.
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)
What do you call the type of event where more than one event is occuring?
Compound event.
