Probability Pop Flashcard

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

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

Back

The probability of an event is calculated as P(E) = Number of favorable outcomes / Total number of possible outcomes.

Front

What is the probability of spinning a specific color on a spinner with equal sections?

Back

The probability is calculated by dividing the number of sections of that color by the total number of sections.

Front

How do you calculate the probability of choosing a specific letter from a set of letters?

Back

Count the number of times the letter appears and divide by the total number of letters.

Front

What is the probability of rolling an even number on a standard six-sided die?

Back

There are three even numbers (2, 4, 6) out of six possible outcomes, so the probability is 3/6 or 50%.

Front

What is the probability of rolling greater than a 1 on a single die?

Back

There are five outcomes greater than 1 (2, 3, 4, 5, 6) out of six possible outcomes, so the probability is 5/6.

Front

What is experimental probability?

Back

Experimental probability is calculated based on the actual results of an experiment, defined as the number of times an event occurs divided by the total number of trials.

Front

How do you find the probability of an event that has not occurred in an experiment?

Back

You can find it by subtracting the experimental probability of the event that has occurred from 1.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes in a perfect scenario, while experimental probability is based on actual outcomes from experiments.

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.
