Answer:
Step-by-step explanation:
Experimental probability is based on what has happened already.
Theoretical probability is what should happen.
Example, a coin has 2 sides:
head or tail
The theoretical probability of flipping a head in a flip is:
1/2
But say, an experiment had a coin flipped 10 times and it came 6 heads and 4 tails, the probability of head would then be:
6/10 = 3/5
A bit different than the theoretical one because it is the experimental probability.
Now, back to our question -----
76 times rolled (76 trials total)
2 appeared "24" times (24)
<u>P(rolling a two) = 24/76 = 6/19</u>
THis is the experimental probability of the experiment of 76 trials.
