Theoretical
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"? (Hint: make a list of outcomes before finding probability)
1/8 or 0.125, or 12.5%
What is the difference between experimental and theoretical probability.
Experimental is based on results and theoretical is based on what should happen
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
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?
1/2, or 0.50, or 50%
You throw a dart at the dart board with the following results: 1-blue 3-red 4--wall. What is the probability that your next dart will hit the wall?
1/2
What is the number of possible outcomes for spinning one spinner with 8 equal sections and another spinner with 6 equal sections?
48 possible outcomes
Define "experimental probability."
The probability of what actually occurs.
How likely is it that a number cube is tossed and lands on 3?
Unlikely
What is the probability of rolling an odd number or a 2 with a standard number cube?
2/3, or 0.67, or 67%
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%
What are the outcomes for a 10 sided di?
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
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. What is the probability that the marble taken out was red or green.
5/6, or 0.83, or 83%
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%
In how many ways can you spin a multiple of two on a spinner numbered 1-8?
1/2
Define "outcome."
The possible result of an experiment
How likely is it that a number cube is tossed and lands on any number 1-6?
Certain
Jarvonya spins a spinner with 5 equal sections numbered 1-5 and she spins another spinner with 5 equal sections with the letters A-E. What is the probability she will spin a 4 and a B? (Hint: make a list of outcomes before finding probability)
1/25 or 0.04, or 4%
What is the p(I) in the word MISSISSIPPI?
4/11
Define "favorable outcome"
The outcome that you want to get

unlikely
