Probability Activity for Class V

​Probability

Blaise Pascal (1623-1662) and Pierre de Fermat (1601-1665) were two seventeenth century French mathematicians who were the founders of Probability Theory. Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes. As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.

​A probability spinner is a simple, often circular, device used to represent and explore probability in a visual and interactive way. It consists of several equally sized, distinct sections or sectors, each of which can be a different color or have a different label. The spinner is designed to be spun or rotated, and where it stops or points to after spinning is used to determine the outcome of a probability experiment.
