There are two spinners. The first spinner has three equal sectors labeled 1, 2 and 3. The second spinner has four equal sectors labeled 3, 4, 5 and 6. The spinners are spun once. What is the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner?

Ten slips of paper labeled from 1 to 10 are placed in a hat. The first slip of paper is not replaced before selecting the second slip of paper. What is the probability of selecting an odd number followed by an even number?

A group of children were asked if they like eating cupcakes or brownies. The table shows the probabilities of the results. Like cupcakes Do not like cupcakes Total Like brownies 0.15 0.15 0.3 Do not like brownies 0.35 0.35 0.7 Total 0.5 0.5 1 Which statement is true?

Liking cupcakes and brownies are independent since P(cupcakes|brownies) = P(cupcakes) and P(brownies|cupcakes) = P(brownies) .

Which events are independent? Select each correct answer.

Two spinners are spun at the same time. A six-sided number cube is rolled and a coin is flipped.

Which statement best explains conditional probability and independence?

When two separate events, A and B, are independent, P(A|B)=P(A) . This means that the probability that event B occurred first has no effect on the probability of event A occurring next.

One spinner has three equally sized sectors numbered 1, 2, and 3. A second spinner has two equally sized sectors labeled Top (T) and Bottom (B). Each spinner is spun once. What is the sample space of outcomes?

{B1, B2, B3, T1, T2, T3}

The probability of choosing two green balls without replacement is 11/50 , and the probability of choosing one green ball is 12/25 . What is the probability of drawing a second green ball, given that the first ball is green?
