Likelihood & Probability
What likelihood describes an event that has a 35% chance of happening?
Unlikely
What 3 words did we use to describe Theoretical Probability?
Equally Likely Outcomes
What 3 words did we use to describe Experimental Probability?
Observing Repeated Trials
There are green and red apples on the tree.
P(picking green apple) = 6 out of 10
Write another probability statement to complete a probability model.
P(picking red apple) = 4 out of 10
Which female gymnast has won the most Olympic gold medals?
Simone Biles (23)
What likelihood describes flipping a coin and it lands head up?
As likely as not (or 50-50)

1 out of 6 -OR- about 17%
Is Experimental Probability the actual probability or the estimated probability?
Actual probability

What Providence Catholic High School alum played goalie for the U.S. Men's Soccer Team?
Brad Guzan
What percent would you use to describe an impossible event?
0%
If you have a standard number cube with numbers 1-6. What is the theoretical probability of rolling an odd number?
3 out of 6 -OR- 50%
The theoretical probability of flipping tails is 50%. Todd flipped a coin 3 times and got tails all 3 times so he says the probability of getting tails is 100%. What is wrong with Todd's results?
He only flipped the coin 3 times. That's not enough. He needs MORE TRIALS.
You want four scoops of ice cream on a cone. (It's not weird, you just love ice cream). And you have 3 different flavors to choose from: chocolate, vanilla and strawberry. How many different combinations could you have? (Can be same flavor or different flavor)

6 out of 9 -OR- two thirds -OR- about 67%
If you have a 12 sided solid with equal sized faces, what is the theoretical probability of rolling a number less than 5?
4 out of 12 -OR- one third -OR- about 33%
Each friend flipped a coin 50 times. Todd got heads 33 times. Jenna got heads 18 times. Bob got heads 27 times. Who had a relative frequency closest to the theoretical probability?
Bob (Theoretical probability is 25 heads out of 50)
An old spinner had 4 sections with sections of red, yellow, blue and green. A new spinner has 5 sections of red, yellow, blue, green AND orange. You win if the spinner lands on blue. Which spinner, the old or new, gives you the higher probability of winning?
Old b/c it has fewer sections.
OLD: 1 out of 4 = 25%
NEW: 1 out of 5 = 20%
Who is the all-time leading scorer in the WNBA?
Diana Taurasi
Steve has a spinner with 10 equal sized sections. There are 6 blue sections and 4 red sections. Is Steve's spinner fair?
No b/c there are more blue sections. There would need to be 5 and 5.
Based on the theoretical probability of flipping heads, if there is a coin flipping game at the carnival, about how many winners would you expect to win if 800 people played the game?
400 -OR- Half
Bob kept track of who won the carnival game all day. He recored that 10 out of 40 people won. How many winners should Bob expect to win if 1,000 people play the game?
250
