Independent Probability Practice

What is the definition of sample space?

• the set of all possible outcomes of a simple or compound experiment

• the space in which you write a probability answer

• the set of all the prime numbers

• the space between the probability of 0 and 1

What is the definition of probability?

• the likelihood something could happen

• the likelihood something did occur

• Probability?!

You pick one nail color and replace it.

Nail colors:

2 pink

3 green

4 red

1 glitter

P( pink, then red). Simplify if necessary.

• 1/5

• 8/100

• 2/25

• 4/10

What is the probability of the arrow stopping on “X” on the first spin and “F” on the second spin?

• 5/6
• 1/36
• 1/3
• 1/6

Based on the picture, find the probability if I roll a 5 on the number cube, and spin a blue letter.

• ⅙ x ¼ = 1/24
• 5/6  x  1/4 = 5/24

What is the probability of spinning a 2, then spinning again and getting a 4?

• 1/5
• 1/10
• 1/25

What is the probability of spinning green?

• 0
• 1/4
• 1/2
• 3/4

One of the possible results of an action.

Example: Landing on heads when flipping a coin.

• Outcome

• Sample Space

• Probability

• Event

What does "certain" mean?

• The event will never happen

• The event has made up it's mind

• The event will definitely happen

• The event is still deciding

an event with a probability of zero

• impossible

• mutually exclusive

• outcome
