T-Mobile LTE 4:31 PM Done 1 of 2 Guided Practice 1. An ice cream store offers waffle cones or sugar cones. Each is equally likely to be chosen. Describe a model that could be used to simulate this situation. Based on your simulation, how many people must order an ice cream cone in order to sell all possible combinations? (Examples 1 and2) 2. An electronics store has determined that 45% of its customers buy a wide-screen television. Describe a model that you could use to find the experimental probability that the next three television-buying customers will buy a Rate Yours How well de y that applies 3, a Building on the Essential Question Explain how using a simulation is related to experimental probability. For more help access a Perso 744 Chapter 9 Probability 4 ]Explanation / Answer
1) The probability of purchasing a waffle cone is 50% or 1/2. The probability of purchasing a sugar cone is 50% or 1/2.Consider a fair coin with heads representing waffle cones and tails representing sugar cones.Toss the toin. If heads is obtained,customer purchases waffle cone. If tails is obtained, customer purchases sugar cone.
Since there are 2 outcomes, the simulation must be carried out twice to cover all combinations.If 2 simulations, then possibilities are (Sugar, Waffle)(Sugar, Sugar),(Waffle, Sugar),(Waffle, Waffle).
2) The probability of purchasing a wide-screen TV is 45% or 9/20. The probability of not purchasing a wide-screen TV is 55% or 11/20.Let 9 marbles represent wide-tv and 11 marbles represent non wide-tv. Place the 20 marbles in a bag and pick one marble to simulate first customer. Replace the marble and pick-again to simulate second customer. Replace the marble and simulate the third customer. Then multiply the probabilities to find the probability of 3 customers purchasing wide-screen TV.
3) Experimental probability refers to the probability of an event occurring when an experiment is conducted. A simulation is an experiment that is designed to act out a given situation. Simulation often use models to act out an event that would be impractical to perform.
If you consider question number 2, it is impractical to go and purchase TV's. Hence to determine the experimental probability, we use simulation.
