Theoretical
Keira is spinning a spinner. that has 4 equal sections labeled A-D. What is the probability the spinner will land on the letter "A"?
1/4 or 25% or .25
Jack has a spinner with 5 equal sections, each a different color. After 10 spins, the pointer had landed on red 4 times. What was his experimental probability of landing on red?
4/10 or 2/5
Define "theoretical probability."
It is the probability of what should occur/ likeliness of event happening based on all possible outcomes.
How likely is it that a coin is flipped and lands on tails?
(never going to happen, unlikely, equally likely, very likely, always going to happen)
Equally likely
The classic wood carousel at Carousel Park in Hampton, VA has 32 jumping horses and 16 standing horses (48 total). What is the probability of randomly selecting a jumping horse?
32/48 or 2/3
Gaige flips a coin 100 times. He gets heads 42 times, and tails 58 times. What is the experimental probability of getting heads?
42/100 = 21/50
Define "experimental probability."
The probability of an event happening
How likely is it that a number cube is tossed and lands on 3?
(never going to happen, unlikely, equally likely, very likely, always going to happen)
Unlikely
What is the probability an odd number (1,3,5) on a 6 sided die.
3/6 or 1/2
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
Give an example of a probability of an experiment that has a 0% chance of happening.
TBD
How likely is it that a number cube is tossed and it lands on 8?
(never going to happen, unlikely, equally likely, very likely, always going to happen)
never going to happen
Nick spins a spinner with 5 equal sections numbered 1-5. What is the theoretical probability of landing on an even number (2,4,6)
3/6, 1/2
Genny flipped a coin 10 times and got tails 3 of those times. What is the experimental probability of tails?
3/10
What is the formula for Theoretical Probability
# favorable outcomes/# possible outcomes
How likely is it that a number cube is tossed and lands on any number 1-6?
(never going to happen, unlikely, equally likely, very likely, always going to happen)
Certain

2/6 or 1/3
Siena has a spinner with 5 equal sections, each a different color. After 10 spins, the pointer had landed on yellow 2 times. What is the experimental probability of landing on yellow.
2/10 or 1/5
How likely is it that a number cube lands on 2 and a coin lands on heads?
(never going to happen, unlikely, equally likely, very likely, always going to happen)
unlikely
