Simple and Compound Independent Probability

Front

What is independent probability?

Back

Independent probability refers to the likelihood of an event occurring without being affected by the occurrence of another event.

Front

What is the formula for calculating the probability of two independent events occurring together?

Back

P(A and B) = P(A) * P(B)

Front

What is the probability of spinning an even number on a spinner with numbers 1 to 6?

Back

50% (There are 3 even numbers: 2, 4, 6 out of 6 total numbers.)

Front

What is the probability of rolling a 1 on a number cube?

Back

1/6 (There is 1 favorable outcome out of 6 possible outcomes.)

Front

If the probability of event A is 1/4 and the probability of event B is 1/3, what is the probability of both A and B occurring?

Back

1/12 (P(A and B) = P(A) * P(B) = 1/4 * 1/3 = 1/12)

Front

What is the probability of drawing a letter other than 'A' from the word 'ALGEBRA'?

Back

5/7 (There are 5 letters that are not 'A' out of 7 total letters.)

Front

What is the probability of the arrow stopping on '1' on the first spin and '6' on the second spin?

Back

1/36 (P(1) = 1/6 and P(6) = 1/6, so P(1 and 6) = 1/6 * 1/6 = 1/36)

Front

What is the probability of spinning a section labeled 'A' on a spinner with 4 sections?

Back

1/4 (There is 1 favorable outcome out of 4 possible outcomes.)

Front

What is the probability of rolling a number cube and getting a number less than 3?

Back

1/3 (The favorable outcomes are 1 and 2, which are 2 out of 6 total outcomes.)

Front

What is the probability of spinning a number greater than 4 on a spinner numbered 1 to 6?

Back

1/3 (The favorable outcomes are 5 and 6, which are 2 out of 6 total outcomes.)
