To state: The number of times a customer have to spend over $50 in order to get all 3 different discount offers if a grocery store is giving away scratch-off tickets to each customers when they spend over $50 and there are three different discount offers randomly and equally distributed among scratch-off tickets.
A person needs to spend $50 nine times to get three different discount offers.
Given information:
A coach wants to select 5 of his 16 players at random to help with a youth basketball camp this weekend. He assigns a two-digit number from 01 to16 to each player.
Explanation:
Simulation is a technique that is used to act out a problem by conducting experiments and its outcomes are analogous to the original problem.
Students can estimates a probability using many trails rather than determine probabilities theoretically while using simulation.
Choose a number between 1 and 9. Draw a random number; the first discount offer is represented by the number between 1, 2, and 3; the second discount offer is represented by the number 4, 5; and the third discount offer is represented by the number 7, 8.
Each number has an equal chance of being selected. The result of the first trial is shown below:
The result shows that a person has to spend
Now repeat the simulation several times.
Let’s conduct the simulation 24 more times and the result will indicate that a person can expect to spend $50 following number to get three different discount offers:
The number of spend over $50 to get three different discount offers is:
Therefore, on an average, a person needs to spend $50 nine times to get three different discount offers.
