What is the formula for calculating probability? |
Card: 1 / 40 |
|
|
P(E) = (Number of favorable outcomes) / (Total number of possible outcomes) |
Card: 2 / 40 |
|
|
True or False: A probability value of 0 indicates that an event is definitely going to happen. |
Card: 3 / 40 |
|
|
False. A probability value of 0 means the event is impossible. |
Card: 4 / 40 |
|
|
Fill in the blank: The set of all possible outcomes of a random experiment is called the ______. |
Card: 5 / 40 |

|
Which of the following is a random experiment? A) Predicting the weather B) Tossing a coin C) Rolling a die D) Both B and C |
Card: 7 / 40 |
|
|
D) Both B and C |

Probability |
Card: 10 / 40 |
|
|
What does it mean if an event has a probability of 1? |
Card: 11 / 40 |
|
|
The event is certain to happen. |
Card: 12 / 40 |
|
|
Fill in the blank: The number of times an event occurs divided by the total number of trials gives us the ______ probability. |
Card: 13 / 40 |
|
|
Experimental |
Card: 14 / 40 |
|
|
True or False: Experimental probability is always the same as theoretical probability. |
Card: 15 / 40 |
|
|
False. Experimental probability may differ from theoretical probability, especially with fewer trials. |
Card: 16 / 40 |
|
|
If you flip a coin 10 times and get heads 7 times, what is the experimental probability of getting heads? |
Card: 17 / 40 |

|
|
C) Edges |
Card: 38 / 40 |
|
|
What does an increase in the number of trials do to the experimental probability? |
Card: 39 / 40 |
|
|
