What is the probability of spinning a 5 as a fraction, decimal and a percent? Round to the nearest hundredths place if needed.
5/12= 0.41666.. = 41.7%

Darian made 24 of the 32 free throws he attempted. What is the experimental probability of him making the next shot written as a fraction, decimal, and percent? Round to the nearest hundredths place if needed.
24/32 = 0.75 = 75%

Define "theoretical probability."
It is the probability of what we expect to occur; no data is collected.

True or False: Likely is the same as 50% probability.
False

A set of cards includes 15 yellow cards, 13 green cards, and 12 blue cards. Which card color has a probability of 3/10?
Probability of drawing a blue card

In a soccer shoot-out, Bryan made 4 out of 9 shots. What is the experimental probability that he will not make his next shot?
5/9 = 0.55... = about 56%
200
Define "experimental probability."
The probability of what actually occurs; probability is calculated after collecting data

What is the likelihood of spinning a 3?
What is likely?

Label the following as uniform or non-uniform probability: A) Flipping a coin, B) Selecting an odd number from numbers 1-13, C) Picking a student from 10 sixth graders, 7 seventh graders, 7 eighth graders
Her prediction was higher than her actual results.

There are 8 green marbles, 7 blue marbles, and 6 red marbles in a jar. What is the probability of not drawing a red marble?
15/21 = 5/7

Bryan made 26 out of 50 free-throw attempts. If Bryan shoots the ball 100 times, about how many free-throws can you expect him to make?
52 free throws; P(making free throw) = 26/50 = 52/100

Define sample space.
All the possible outcomes of an experiment.

In the game of chess the pieces come in black and white. For each color, there are the following pieces: 1 - queen, king 2 - rooks, bishops, knights, 8 - pawns What is the probability of randomly selecting a rook in simplest form?
4/32 = 1/8

If you spin the spinner 48 times, how many times can you expect to land on 11?
6

"Cameron hit 5 homeruns out of 10 swings in the Homerun Derby at his school. The probability of his next swing being a homerun is 1/2." Student A read this and said it's theoretical probability. Student B said it's experimental probability. Who is correct? Explain why.
Student B because the word problem has the data collected from Cameron performing the event (hitting baseballs). They calculated the probability based on the repeated experiment.

There are 3 green marbles, 2 red marbles and 15 blue marbles. Give a scenario that is unlikely to happen?
Draw a red marble OR draw a green marble

An airline food service finds that a recent flight of 120 passengers ordered dinner. 25 people ordered lasagna. Based on this data, how many lasagna dinners are likely to be needed for a flight with 360 passengers?
75 lasagna dinners; P(lasagna dinner ordered) = 25/120 = 75/360

In Ms. McCarthy's Language Arts class students created projects to share with the class. There are 10 boys and 15 girls. What is the probability of not drawing a boy to present first in decimal form? Write in percent form.
15/25 = 60/100 = 60%

Jason rolls a number cube 42 times. About how many times can he expect to roll an odd number GREATER THAN 1?
14 times; P(odd number greater than 1) = 2/6 = 14/42

Tell the difference between uniform and non-uniform probability.
Uniform probability has outcomes that all have the same probability of occurring. Non-uniform has outcomes that do not have the same probability of occurring (not all equally likely to occur).
