Basic Probability

Front

What is the probability of rolling an even number on a single die?

Back

P(even number) = 1/2

Front

When rolling a pair of dice, what is the probability of the sum being greater than 9?

Back

P(sum > 9) = 1/6

Front

If you draw two slips from a box containing slips marked 1 to 5, how many possible outcomes are there?

Back

There are 25 possible outcomes.

Front

What is the probability of rolling a number greater than 3 or an odd number on a single die?

Back

P(number > 3 or odd) = 5/6

Front

What is the probability of drawing a diamond from a standard deck of cards?

Back

Front

Define probability in the context of a random experiment.

Back

Probability is the measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a random experiment.

Front

Explain the difference between independent and dependent events.

Back

Independent events do not affect each other's outcomes, while dependent events do.

Front

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

Back

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

Front

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

Back

P(rolling a 3) = 1/6.
