Exp Vs Theorhetical Probability

Experimental Probability is:

• What Will happen 
• What actually happens
• What should happen
• What I think Happens

A coin is tossed 18 times. It lands on heads 12 times. What is the experimental probability of the coin landing on tails? simplify the fraction!

What is Theoretical Probability?

• The ratio of favorable outcomes to the total number of possible outcomes
• The ratio of favorable outcomes to the total number of trials in an experiment
• In probability, a controlled, repeated process (such as repeatedly tossing a coin).
• A single possible result.

Tammy rolled a die five times.

Here is what she got on her five rolls: 1, 3, 3, 4, & 4

Find the experimental probability:

P(3) =

• 3/5

• 1/6

• 2/5

• 1/3

What is the probability of spinning a 2 on the spinner?

• 1/2

• 1/3

• 1/8

• 1/4

The spinner shown is spun once.

P(greater than 10)

• 1/8

• 0

• 8/8

• 1/2

There is 4 blue marbles, 6 red marbles, 2 yellow marbles and 1 white marble in the bag. What is the probability of randomly choosing a yellow marble?
