Answer:
Probability is the answer.
Step-by-step explanation:
The occurrence of a chance event during one trial does not influence the results of later trials. This is an important principle regarding- probability.
Trials are independent if the outcome of one trial does not influence the outcome of any other. Events A and B are independent if the equation P(A∩B) = P(A) P(B) is true. To find the joint probability or to know if they are happening together, we multiply the probabilities.
