Probability Sample Spaces and Outcomes

The chart below represents the number of marbles in a jar.
P(green) = 

• 5/19

• 10/28

• 5/14

• 17/38

What is the probability of getting any letter that is not A?

• 6/8

• 3/4

• 2/8

• 1/4

A bag has 3 red marbles, 2 blue and 4 green and 1 yellow. What is the theoretical probability of pulling a red?

• 30%

• 3/9

• 1/4

• 25%

P(not A) = 

• 6/8

• 3/4

• 2/8

• 1/4

Find the probability of rolling greater than a 1 on a single die.

• 6/6

• 5/6

• 4/6

• 1/6

Find the probability of not rolling a 2 on a single die.

• 1/6

• 2/6

• 5/6

• 2

Determine whether the event is impossible, unlikely, as likely as not, likely, or certain. You flip a fair coin and the coin will land heads up.

• impossible

• unlikely

• as likely as not

• likely

Find the experimental probability:

Roll dice: 1, 3, 3, 4, 4

P(1) =

• 3/5

• 1/6

• 2/5

• 1/5

Probability is defined as...

• the set of all possible outcomes.

• the likelihood that an event will happen.

• the fundamental counting principle.

Tree diagrams are useful because...

• they are cool to draw.

• they only show you the best choices.

• they show you all possible outcomes.
