Probability Test Review

Front

What is the theoretical probability of an event?

Back

The theoretical probability of an event is the ratio of the number of favorable outcomes to the total number of possible outcomes, assuming all outcomes are equally likely.

Front

What is the experimental probability of an event?

Back

The experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials conducted.

If a coin is tossed, what is the theoretical probability of getting heads?

Back

1/2

Front

If a coin is tossed 10 times and results in 7 heads, what is the experimental probability of getting heads?

Back

7/10

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

Front

In a bag with 4 green, 2 red, and 4 purple tokens, what is the theoretical probability of drawing a red token?

Back

1/5

Front

If Lisa drew a red token 8 times out of 30 trials, what is the experimental probability of drawing a red token?

Back

2/15

Front

What does it mean if the theoretical probability is greater than the experimental probability?

Back

It suggests that the actual outcomes in the experiment did not match the expected outcomes based on theoretical calculations.

Front

What is the probability of not drawing a specific token (e.g., token D) if there are 6 total tokens?

Back

P(not D) = (Total tokens - Tokens of type D) / Total tokens.

Front

How do you express probability as a fraction?

Back

Probability can be expressed as a fraction where the numerator is the number of favorable outcomes and the denominator is the total number of outcomes.
