Maria is flipping a coin and spinning a spinner. The spinner has 4 equal sections labeled A-D. What is the probability the coin will land on heads and the spinner will land on the letter "A"?
1/8 or 0.125, or 12.5%

1/8
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 "theoretical probability."
It is the probability of what should occur.
How likely is it that a coin is flipped and lands on tails?
Equally likely

Define "experimental probability."
The probability of what actually occurs.

1/6
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.
How likely is it that a number cube is tossed and it lands on 8?
never going to happen
There are 3 red marbles, 2 green marbles, and 1 yellow marble in a box. One marble is taken out and not replaces. A second marble is then taken out and not replaced. What is the probability both marbles that were taken out are red?
1/5, or 0.20, or 20%
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 "independent event."
When one event occurs and the item is replaced before the second event occurs.
How likely is it that a number cube is tossed and lands on any number 1-6?
Certain
The theoretical probability of tossing a heads on a coin is 1/2. A coin was tossed 50 times and landed on heads 28 times, which is the experimental probability. Which probability was higher, theoretical or experimental?
Define "dependent event."
When one event occurs and that item is not replaced before the second event occurs.
What is the probability of a number cube landing on a 2 and a coin landing on heads? Express as a fraction.
1/12
