Area of a Circle | 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 🗑
|
