Alg 2 Unit 5 Review Part 2

One spinner has three same-sized sectors numbered 1, 2, and 3. A second spinner has two same-sized sectors labeled Top (T) and Bottom (B). Each spinner is spun once.

What is the sample space of outcomes?

• {1, 2, 3, T, B}
  

• {B1, B2, B3, T1, T2, T3}
  

• {BT, 123}
  

• {BT,BB,TB,11,12,13,21,22,23,31,32,33}

A coin is flipped three times.

What is the number of possible outcomes?

• 2

• 4

• 8

• 16

A six-sided number cube is rolled twice.

What is the number of possible outcomes?

• 6

• 12

• 36

• 216

There are two spinners. The first spinner has three same-sized sectors labeled 1, 2, and 3. The second spinner has four same-sized sectors labeled 3, 4, 5, and 6. Spinners are spun once.

How many outcomes do not show an even number on the first spinner and show a 6 on the second spinner?

• 2

• 3

• 5

• 7

Which events are independent?

Select each correct answer.

• Two six-sided number cubes are rolled.

• Three red marbles are drawn from a bag with replacement.

• Two blue cards are drawn from the bag without replacement.

• Three coins are tossed at the same time.

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?

Kim rolls a six-sided number cube labeled from 1 to 6.

What is the probability that she rolls a number greater than 3 or a 1?

There are twelve cards labeled from 1 to 12 in a box. A card is randomly drawn from the box.

What is the probability of getting a multiple of 3 or an odd number?

 

A and B are two events.

Select the correct responses to fill in the blanks:

Events A and B are ______ because _____.

• independent

• not independent

• P(A|B) = P(A)
