Exploring Experimental Probability of Simple Events

The video tutorial covers experimental probability of simple events, starting with a paper cup experiment to demonstrate how outcomes can vary. It explains how to calculate experimental probability by comparing event occurrences to total trials. The tutorial includes examples with marbles and a spinner, showing how to predict outcomes using simulations. It concludes with a demonstration using a number cube to predict the probability of different outcomes.

What are the possible outcomes when tossing a paper cup?

• Open end up, open end down, on its side

• Open end up, closed end up, on its side

• Open end down, closed end down, on its side

• Open end up, open end down, closed end down

In the paper cup tossing activity, which outcome was most likely?

• Open end up

• Open end down

• All equally likely

• On its side

What does the sum of all probabilities in an experiment equal to?

• 1

• The total number of outcomes

• 0

• The total number of trials

How do you calculate the experimental probability of an event?

• Number of times an event occurs divided by the number of trials

• Number of trials divided by number of successes

• Number of desired outcomes divided by total outcomes

• Total number of outcomes divided by number of times an event occurs

How can a standard number cube be used to predict the outcome of drawing a foam ball from a toy machine?

• All of the above

• Rolling the cube 50 times to determine the experimental probability

• Rolling the cube once and selecting the color assigned to the number

• Assigning numbers 1 & 2 to red, 3 & 4 to white, and 5 & 6 to blue
