Probability

January 14, 2014

Probability: This is defined by the measure of how many times an event is likely to occur out of the number of possible outcomes.

Our first task with a partner was to gather an amount of colored goldfish and determine the probability of choosing a certain color.
I'm familiar with probabilities so this task was easy for me.

For our problem there were 48 goldfish and the green ones represented sick fish and the other colors represented healthy fish. We counted 10 green fish so the healthy fish amount is 48-10 which is 38 healthy fish. Now let's compute the probability that a fish in our sample is healthy. If 38 out of 48 fish are healthy, the probability is then 38/48 or when reduced 19/24. This means that for 24 fish that are counted, 19 of them will be healthy. Therefore, the probability of choosing a sick fish is 10/48 or when reduced 5/24. When 24 fish are counted, 5 of them will be sick.

Here's some great games to play with the elementary kids to learn about probability!
