Test on Normal Curve, Theoretical and Experimental Probability

Theoretical probability is based on ___________

• What we think will happen without experiments

• Your tally after doing the experiments

Experimental probability is based on

_____________

• What we think will happen without experiments

• Your tally after doing the experiments

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

• 3/10

• 3/6

• 1/9

• 1/3

The probability of flipping a coin and landing on tails is 1/2.
If you flip the coin 100 times, approximately how many times could you expect to land on tails?

• 50 times
• 100 times
• 200 times

Experimental Probability is:

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

A dice was rolled five times and the following were rolled: 1, 3, 3, 4, 4

Based on this information, find the experimental P(1).

• 3/5
• 1/6
• 2/5
• 1/5
