Experimental Vs. Theoretical Probability
b. Joan picks a random counter out of a bag 
    10 times, and she got a yellow counter 
    7 times. What is the experimental
    probability of picking a yellow?
a.
What is the theoretical probability of picking a yellow counter in simplest form?

he can get when flipping a coin.

probability of getting tails?
How many times would he expect to get the color red
if he did 30 spins?

Diana completes an experiment of spinning athree-colored spinner 15 times. She expected to get aprobability of 1/3 for each color, but her numberswere really off. She got 0% probability for red, 60% for green, and 40% for blue. 
How could she get her experimental probability closer to her theoretical probability?
She should complete more trials.
She could spin a different spinner.
She needs to dice instead.
She needs to spin fewer times.
the number 7 will appear more than the number 1.
the theoretical probability is always less than the
experimental probability
the more times the cube is rolled, the closer the
experimental probability gets to the theoretical
probability
the theoretical probability is always greater than
the experimental probability.
Which of the following statements is TRUE?

When rolling a number cube...
Theoretical Probability
Mr. Whatley rolled a fair number cube 50 times.  The
number 4 came up 10 times.  Calculate the theoretical & experimental probabilities of rolling a 4 in simplest form.
Experimental Probability
Anthony is going to spin the 6-sectioned spinner below to see if he really will get the colorYellow 1/6 of the time. 
How many times should he spin the spinner for the outcome of his experiment to best match his theory?
60 spins
6 spins
600 spins
1 spin
