TEST - Theoretical & Experimental Probability

Probability that is a prediction based on the number of favorable outcomes divided by the total number of possible outcomes is ___________.

• Theoretical

• Experimental

Probability that is based on the actual trial results is _____________.

• Theoretical

• Experimental

Determine the type of probability:

Damon flipped a coin 50 times and got 31 heads.

Based on the results, the probability of heads is 31/50, or 62%.

• Theoretical Probability

• Experimental Probability

Determine the type of probability:

The probability of flipping tails is 1/2, or 50%, since the sides of a coin have 1 tails and 1 heads.

• Theoretical Probability

• Experimental Probability

Determine the type of probability:

On a regular number cube, the chance of rolling a 5 is 1/6.

• Theoretical Probability

• Experimental Probability

Determine the type of probability:

Jane rolled a regular number cube 25 times.

Since she rolled an EVEN number 11 times, the probability of EVEN numbers is 11/25, or 44%.

• Theoretical Probability

• Experimental Probability

Determine the type of probability:

A spinner has 4 equal-sized spaces labeled A, B, C, and D.

The chance of landing in any of the spaces is 1/4, or 25%.

• Theoretical Probability

• Experimental Probability

What is the probability of spinning a C on the spinner shown? Total Sections = 12 .

(Reduce fraction)

•  $\frac{1}{2}$  

•  $\frac{1}{4}$  

•  $\frac{1}{5}$

The spinner shown is spun 150 times. What is the best prediction for how many times you would spin an L? Total Sections = 8.

2/8 * 150 =

• 18 times

• 28 times

• 38 times

• 48 times

If 400 people spun this spinner, about how many times would you expect to land on a space with a 1 on it? Total Sections = 10.

3/10 * 400 =

• 4

• 25

• 100

• 120
