Probability Tree Diagram

Front

What is a probability tree diagram?

Back

A visual representation that shows all possible outcomes of an event, helping to calculate probabilities.

Front

What is the probability of rolling a number higher than 3 on a die?

Back

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

Front

What is the probability of flipping a tails with a coin?

Back

There are 2 outcomes (heads or tails) and 1 favorable outcome (tails), so the probability is 1/2.

Front

How do you calculate the combined probability of two independent events?

Back

Multiply the probabilities of each event. For example, P(A) * P(B).

Front

What is the total number of outcomes when rolling a die and flipping a coin?

Back

There are 6 outcomes from the die and 2 from the coin, so 6 * 2 = 12 total outcomes.

Front

What is the probability of rolling a number less than 6 on a die?

Back

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

Front

What does 'more likely' mean in probability?

Back

It means the event has a higher chance of occurring compared to another event.

Front

What does 'certain' mean in probability?

Back

It means the event will definitely happen, with a probability of 1.

Front

What is the probability of rolling a 2 on a die?

Back

There is 1 favorable outcome (2) out of 6 possible outcomes, so the probability is 1/6.

Front

What is the probability of selecting a boy from a group of 35 students with 12 girls?

Back

There are 23 boys, so the probability of selecting a boy is more likely than selecting a girl.
