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 probability of an event that is certain to happen?

Back

The probability of an event that is certain to happen is 1.

Front

What is the probability of an impossible event?

Back

The probability of an impossible event is 0.

Front

How do you calculate the probability of a single event?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is the probability of landing on a specific color in a spinner divided into equal sections?

Back

Probability = 1 / (Number of sections). For example, if there are 8 sections, the probability of landing on one specific color is 1/8.

Front

If a coin is tossed, what are the possible outcomes?

Back

The possible outcomes are Heads (H) and Tails (T).

Front

What is the probability of getting heads when tossing a fair coin?

Back

The probability of getting heads is 1/2.

Front

What is the combined probability of two independent events occurring?

Back

The combined probability of two independent events A and B is P(A) * P(B).

Front

If a coin is tossed 4 times, what is the total number of possible outcomes?

Back

The total number of possible outcomes is 2^4 = 16.

Front

What is the probability of getting tails if a coin is tossed 40 times and lands on tails 18 times?

Back

Probability of tails = (Number of tails) / (Total tosses) = 18/40 = 45%.
