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 does P(A) represent in probability?

Back

P(A) represents the probability of event A occurring.

Front

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

Back

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

Front

What is the probability of rolling a 6 on a fair 6-sided die?

Back

Front

If a die is rolled 60 times, how many times would you expect to roll a 6?

What is the probability of selecting an electric vehicle from a group of vehicles?

Back

P(electric) = (Number of electric vehicles) / (Total number of vehicles).

Front

What does 'or' mean in probability?

Back

In probability, 'or' means to consider the likelihood of either event occurring, often calculated using the addition rule.

Front

What is the addition rule in probability?

Back

The addition rule states that P(A or B) = P(A) + P(B) - P(A and B).

Front

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

Back

For independent events A and B, P(A and B) = P(A) * P(B).

Front

What is the probability of selecting a gas or hybrid vehicle?

Back

P(gas or hybrid) = P(gas) + P(hybrid).
