This video tutorial by Mr. Hul covers Lesson Four on calculating probabilities for chance experiments with equally likely outcomes. It begins with an introduction to probability concepts and proceeds with a random cube drawing experiment to demonstrate practical application. The video analyzes the experimental results and compares them with theoretical probability. Additional exercises include a coin flipping experiment, dice rolling, letter selection, and coloring squares to further explore probability concepts. The lesson concludes with a spinner game scenario to calculate probability.

What is the basic formula for calculating the probability of an event?

• Number of favorable outcomes multiplied by total number of outcomes

• Number of favorable outcomes divided by total number of outcomes

• Total number of outcomes divided by number of favorable outcomes

• Total number of outcomes minus number of favorable outcomes

In a chance experiment with replacement, what happens to the number of items in the bag?

• It doubles

• It remains the same

• It increases

• It decreases

If a theoretical probability predicts equal outcomes, what might an experimental probability show?

• Different outcomes due to chance

• No outcomes at all

• Only one outcome

• Always equal outcomes
