If the probabillity that person wins is 0.20 and he wins half games out of 20 then the difference between theoretical probability and experimental probability is 0.30 which is option d.
What is probability?
Probabiity is the chance of happening an event among all the events that are possible. It lies between 0 and 1. It cannot be negative.It is basically the number of items divided by total number of items.
How to calculate probability?
We have been given that probability that person wins is 0.20 and person actualy wins 10 times from 20 times.
Experimental probability=10/20
=0.5
Given theoretical probability=0.20
Difference=Experimental Probability-Theoretical probability
=0.50-0.20
=0.30
Hence if the probabillity that person wins is 0.20 and he wins half games out of 20 then the difference between theoretical probability and experimental probability is 0.30 which is option d.
