If you flip a coin 10 times, about how many times should it land on heads?
You are redoing your bedroom. You've narrowed down to 5 paint colors - mint green, coral, peach, sea green, gray and 3 floor types - tile, wood, carpet. Create a sample space.
Show your boards!
Define "sample space."
Visually showing all the possible outcomes (list, tree diagram, table).
You get to choose 2 ducks from a pool to win a prize. You don't replace the 1st choice. Out of 20 ducks in the pook, 6 have stars on them to indicate winning a prize. The first one you choose wins you a prize! What is the probability that the second duck is also a prize winning duck?
6/20 = 3/10 * 5/19 = 15/190 = 3/38
How likely is it that a number cube is tossed and it lands on 8?
Impossible
At the zoo there is an exhibit and there are 3 times as many blue penguins as there are emperor penguins. The sign says that there are 68 total penguins. How many of each are there? (side note: If there is not a 3 to 1 ratio then the emperor penguins will eat the blue penguins. Fact.)
Blue - 51
Emperor - 17
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.
22 times
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? (Ex: spinning two spinners)
Compound event
There is an 80% chance of a thunderstorm on Saturday. Describe the likelihood that there is not a thunderstorm on Saturday.
There is a 20% chance it will not rain so it is unlikely to rain.
1/10 = 10%
