# Grade 7 Math - Predicting Using Probability

Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times.

## TOPICS RELATED TO PREDICTING USING PROBABILITY

### What are some examples of experimental probability?

For example, if a dice is rolled 6000 times and the quantity 'five' happens 990 instances, thenthe experimental probability that 'five' shows up at the dice is 990/6000 = 0.one hundred sixty five. forexample, the theoretical probability that the variety 'five' suggests up on a cube when rolled is 1/6 = 0.167.

### What are predicted probabilities?

Well, a anticipated opportunity is, essentially, in its maximum basic shape, the chance of an occasion this is calculated from to be had data.

### How do you make predictions using experimental probability?

To make a prediction the use of experimental opportunity, multiply the experimental possibility by means of the variety of trials to get a prediction.
