The video explores the concept of sample space, starting with a simple coin flip example to illustrate the idea of possible outcomes. It then introduces a more complex scenario involving a bakery with different cupcake flavors and sizes, demonstrating how to construct a sample space using tree diagrams, grids, and tables. The video concludes by explaining compound sample spaces, which consider multiple variables.

What is a sample space in the context of a probabilistic trial?

• The probability of an event occurring

• A specific outcome of interest

• The set of all possible outcomes

• A mathematical formula for calculating probabilities

In a coin flip, what are the possible outcomes that make up the sample space?

• Heads, Tails, and Edge

• Tails only

• Heads only

• Heads or Tails

How many possible outcomes are there when selecting a cupcake by flavor and size at the bakery?

• 3

• 6

• 9

• 12

Which method can be used to visualize the sample space of cupcakes by flavor and size?

• Pie chart

• Tree diagram

• Bar graph

• Line plot

What is a compound sample space?

• A space that considers multiple ways in which outcomes can vary

• A space where outcomes are not equally likely

• A space used exclusively for complex mathematical computations

• A space with only one variable outcome

How does knowing the sample space help in probability?

• It calculates the mean outcome of trials

• It outlines all possible outcomes to assess probabilities

• It determines the exact probability of complex events

• It predicts future outcomes with certainty

What is the probability of picking a small or chocolate cupcake if all outcomes are equally likely?

• 1/9

• 1/3

• 2/3

• 1/2

Why are sample spaces particularly useful when outcomes are equally likely?

• They eliminate the need for experimental data

• They make it straightforward to calculate the probability of events

• They allow for the visualization of complex data

• They simplify the calculation of mean outcomes
