# Grade 7 Math - Finding the Probability of a Compound Event

Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process. For example, find the approximate probability that a spinning penny will land heads up or that a tossed paper cup will land open-end down. Do the outcomes for the spinning penny appear to be equally likely based on the observed frequencies?

## TOPICS RELATED TO FINDING THE PROBABILITY OF A COMPOUND EVENT

### What is an example of a compound event?

Compound events. an event is an prevalence that may be determined by using a given degree of certainty. as an instance, while we say that the probability of an eventhappening is high or low, we're stating the truth that the occasion may also or may not show up in a given way.

### How do you find the probability of two compound events?

To locate the probability of two independent occasions, multiply the possibility of the first event by way of the chance of the second one event. whilst occasions depend upon each other, they're known as structured occasions.

### How do you find the probability of at least one event occurring?

To find the probability of at the least one of something, calculate the possibility of none and then subtract that end result from 1. that is, p(at least one) = 1 – p(none). topford elements x-data dvds in lots of 50, and that they have a said illness fee of zero.5% so the chance of a disk being defective is 0.0.5.
