**relative probability** This is a topic that many people are looking for. **bluevelvetrestaurant.com** is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, ** bluevelvetrestaurant.com ** would like to introduce to you **Probability Relative Frequency Approach Example**. Following along are instructions in the video below:

“We re going to look at an example of the relative frequency approximation for probability. Probability. And what we re looking at here is a toy table representing the passengers the titanic in the rolls. We see we have the passenger is classified by what class ticket.

They bought first class second class and third class. And we also have them classified across the top..

There by whether they survived or died as a result of the shipwreck. Let s take a look at this example. The example says assuming that one of the 1316. Passengers is randomly selected find the probability that it is a passenger that survives all right well we re going to use the relative frequency approximation and in this approximation.

We say that we want to look at the number of times. The procedure was repeated and divide that into the number of times..

The event occurred. So we have to define what the procedure is and what the event is and then find the probability of that event. The first thing is defining. What the event is and let s see we re looking for the probability looking for the probability.

That is the past that it is a passenger that survived so a is going to be the event that we select a passenger that survives okay so that is the event. The event..

A is we select a passenger that survives. What we wanted we want to find the probability of a so we re looking for the probability of a and the formula says the probability of a is the number of times a occurs. So we need to find the number of times a occurs well if i look at this chart. I see this entire row here or this entire column here represents.

People that survived so looking at that entire column. I ll find the survivors of the shipwreck and if you do that some you get 498 people survived the shipwreck or a passenger survived the shipwreck because there were also crew members this is just a representation of the passengers and the next thing we need to look at is a number of times..

The procedure was repeated well there they actually specifically asked us to look at one of the 1316. So the number of times. The procedure was repeated is one thousand three hundred and sixteen so it turns out that the probability of event. A so we re putting the event into the probability function and then we re going to use relative frequency to assign a probability to this event and that is going to be four hundred and ninety eight divided by 1316 so what we want to do here is we want to convert this to a decimal and the decimal here is point three seven eight.

So the probability that we select one of these 1316 passengers and just happen to select a passenger that survived is ” ..
