Simple Probability #2

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a ratio of the number of favorable outcomes to the total number of possible outcomes.

Front

What is a spinner in probability?

Back

A spinner is a circular object divided into sections, each representing a different outcome. When spun, it can land on any of the sections.

Front

How do you calculate the probability of a single event?

Back

To calculate the probability of a single event, use the formula: Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What does 'favorable outcomes' mean?

Back

Favorable outcomes are the specific outcomes that we are interested in when calculating probability.

Front

What is the total number of outcomes for a spinner divided into 8 equal sections?

Back

The total number of outcomes for a spinner divided into 8 equal sections is 8.

Front

If a spinner has 2 shaded sections out of 6 total sections, what is the probability of landing on a shaded section?

Back

The probability of landing on a shaded section is 2 out of 6, which simplifies to 1 out of 3.

Front

What is the probability of landing on a non-shaded section if there are 4 shaded sections on a spinner with 8 sections?

Back

The probability of landing on a non-shaded section is 4 out of 8, which simplifies to 1 out of 2.

Front

How do you express probability as a fraction?

Back

Probability can be expressed as a fraction by placing the number of favorable outcomes over the total number of possible outcomes.

Front

What is the probability of landing on either of two outcomes?

Back

The probability of landing on either of two outcomes is the sum of the probabilities of each individual outcome.

Front

If a spinner has 3 sections that are stars and 5 sections that are not, what is the probability of landing on a star?

Back

The probability of landing on a star is 3 out of 8.
