Probability

Front

What is the probability of choosing a specific letter from a word and flipping a coin?

Back

The probability is calculated by multiplying the probability of choosing the letter by the probability of the coin flip.

Front

What is Experimental Probability?

Back

Experimental Probability is what actually happens based on the outcomes of an experiment.

Front

How do you calculate the theoretical probability of an event?

Back

Theoretical probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is the theoretical probability of pulling a red marble from a bag containing 3 red, 2 blue, and 4 yellow marbles?

Back

1/3, since there are 3 favorable outcomes (red marbles) out of 9 total marbles.

Front

What is a sample space in probability?

Back

A sample space is a list of all possible outcomes of an event.

Front

What are the possible outcomes when flipping two coins?

Back

The sample space is HH, HT, TH, TT.

Front

What is the formula for calculating the probability of an event?

Back

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

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual outcomes from experiments.

Front

How do you determine the probability of independent events occurring together?

Back

Multiply the probabilities of each independent event.

Front

What is the probability of rolling a 4 on a standard six-sided die?

Back

1/6, since there is one favorable outcome (rolling a 4) out of six possible outcomes.
