Circumference of a Circle   show
🗑
Area of a Circle   show
🗑
Radius   show
🗑
Diameter   show
🗑
show the chance that something will happen; the ratio of the number of ways an event can occur over the total number of possible outcomes  
🗑
show a list of all the possible outcomes; each outcome should be written in parentheses with a comma between events. For example (Heads, 6) represents flipping a heads on a coin and then rolling a 6 on a number cube  
🗑
show never going to happen; probability = 0 or 0%  
🗑
show definitely going to happen; probability = 1/1 or 1.0 or 100%  
🗑
show the outcome of one event DOES NOT affect the probability of the other event; example: rolling a number cube and then flipping a coin  
🗑
show the outcome of one event DOES affect the probability of the other event; example: picking a jelly bean from a jar, eating it, and then picking a second  
🗑
show what you expect to happen  
🗑
Experimental Probability   show
🗑
Simulation   show
🗑
show 1/2 x 3/6 = 3/12 or 1/4  
🗑
show 5/10 x 4/9 = 20/90 or 2/9  
🗑
Unlikely Event   show
🗑
show Probability is greater than 1/2 (50%) but less than 1 (100%)  
🗑
Simple Interest Formula   show
🗑
show change/original = %/100  
🗑
If the area of a circle = 100pi, find the radius and diameter.   show
🗑
show radius = 6; diameter = 12  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
