Probability Flashcard

Front

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

Back

The probability is \( \frac{5}{6} \) because there are 5 outcomes (2, 3, 4, 5, 6) that are greater than 1 out of 6 possible outcomes.

Front

What is the probability of choosing a letter other than 'A' from the word ALGEBRA?

Back

The probability is \( \frac{5}{7} \) because there are 5 letters (L, G, E, B, R) that are not 'A' out of 7 total letters.

Front

What is the probability of selecting an orange candy from a picture where all candies are orange?

Back

The probability is 100% because all candies are orange.

Front

If you select one shape at random from an array of 16 shapes, what is the probability that it would be a circle if there are 6 circles?

Back

The probability is \( \frac{6}{16} \) or \( \frac{3}{8} \) because there are 6 circles out of 16 total shapes.

Front

If you select a marble without looking, how likely is it that you will pick an orange marble if there are more orange marbles than any other color?

Back

It is 'likely' to pick an orange marble.

Front

Define probability in the context of a single event.

Back

Probability is a measure of the likelihood that a specific 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 formula is \( P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \).

Front

What does it mean if an event has a probability of 0?

Back

It means the event is impossible and will not occur.

Front

What does it mean if an event has a probability of 1?

Back

It means the event is certain and will definitely occur.

Front

What is the probability of rolling a 3 on a single die?

Back

The probability is \( \frac{1}{6} \) because there is 1 favorable outcome (rolling a 3) out of 6 possible outcomes.
