How do you find the probability of rolling an odd number on a standard die?

Back

There are 3 odd numbers (1, 3, 5) on a standard die. The probability of rolling an odd number is 3/6 or 1/2.

What is the probability of rolling a 6 on a standard die?

Back

The probability of rolling a 6 on a standard die is 1/6.

Front

If a die is rolled twice, what is the total number of outcomes?

Back

The total number of outcomes when rolling a die twice is 6 x 6 = 36.

Front

What is the probability of rolling a 6 on the first roll and a number less than 5 on the second roll?

Back

The probability is (1/6) * (4/6) = 4/36 = 1/9.

Front

How do you calculate the probability of independent events?

Back

For independent events, multiply the probabilities of each event.

Front

What is a tree diagram?

Back

A tree diagram is a visual representation of all possible outcomes of an event, showing the paths that can be taken.

What is the probability of getting plain crust with ham on your pizza if there are 10 options?

Back

The probability is 1/10.

Front

How many total outcomes are there when rolling a die and flipping a coin?

Back

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

Front

What is the probability of getting two odd numbers when rolling a die twice?

Back

The probability is (1/2) * (1/2) = 1/4.
