Which fraction is greater? (1/4) or (1/5)
1/4
There's two possible outcomes. Pulling a green marble or a pink marble from the bag. If the theoretical probability of getting a green marble is 20%, what is the theoretical probability of taking a pink marble out of the bag? (Write your answer as a percent)
80%

What is the diameter of a Circle?
The diameter is the length of the line through the center that touches two points on the edge of the circle.
How would we write 1/4 as a decimal?
0.25
If the chance of the spinner landing on green is 1/4, how many times can I theorize for the spinner to land on green if I spun it 120 times?
30 times

If the diameter is 2.4 cm, What is the circumference of the circle? Use 3.14 for PI.
C = 7.536 cm
How would 0.20 be written as a fraction? (Simplifying it is optional!)
20/100 or 1/5
The chance of Rick hitting the ball with his bat in baseball is 20%. If someone were to serve the ball at him 490 times, how many times can he possibly hit the ball using our experimental probability?
34 + 6 - 3

If the radius of 3 congruent/equivalent circles is a total of 9 metres, what is the circumference of 1 circle? Use 3.14 for PI.
C = 18.84 metres
None! They're equivalent.
What is the difference between experimental and theoretical probability?
Simply put, theoretical probability is what we expect to happen with the data we have. While experimental probability is what actually occurs when we try the experiment.

If the diameter of the Circle is 8 cm, What is the area of the circle? Use 3.14 for PI.
Tip: Use the Formula
A = 50.24 cm2
Which of these values is greater? 3/4 or 0.76
0.76
What is an independent and dependent event?
An independent event is an event in which the outcome isn't affected by another event. A dependent event is affected by the outcome of the first event/the experiments before.

Elon wanted to buy 3 telescopes, each with a price of $346. If Elon were to buy all 3 telescopes and give an extra 13% of the total (Generosity), how much money will he have to pay? Make sure to add the extra 13%!
Elon would pay $1172.94
If 5 equivalent small circles circumference can fit in 1 large circles circumference of 359 metres, what is the radius of one small circle? Use 3.14 for PI and round your answer to the nearest tenth.
Radius = 11.4 metres
