What does estimated experimental probability mean please someone answer?

Answer 1

One way of finding the probability is to carry out an experiment repeatedly. Then the estimated experimental probability is the proportion of the total number of repeated trials in which the desired outcome occurs.

Suppose, for example you have a loaded die and want to find the probability of rolling a six. You roll it again and again keeping a count of the total number of rolls (n) and the number of rolls which resulted in a six, x. The estimated experimental probability of rolling a six is x/n.

Answer 2

Estimated experimental probability is one of several ways to find the probability of a given outcome. An experiment is repeated a large number of times (n) and the number of times that the specified outcome happens (s) is recorded. The observed experimental probability is s/n, and as n increases this estimate comes close to the true value.
