Answer: Experimental Probability
Step-by-step explanation:
Theoretical Probability is the theory behind probability. Experimental (empirical) probability is probability calculated during experiments, direct observation, experience, or practice. The empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
Answer:
I'll help out a bit:
Step-by-step explanation:
So ANY number in a square root is irrational(Non-terminating and no pattern)
Pi is also irrational
But ANY number that can be expressed as a fraction is rational(Also Whole numbers, natural numbers, etc.)
Hope this helps!
