Conduct a simulation to estimate how many batteries the company needs topull off the production line in order to be sure of ending up with 10 working batteries.1. Describe how you will use a random number table to conduct this simulation.2. Show three trials by clearly labeling the random number table given below. Specify theoutcome of each trial.Trial 1: 10242 50692 18977 28370 82669 83236 77479 90618 43707 78695Trial 2: 81183 48554 60809 39996 81915 25404 33366 92082 04822 79866Trial 3: 06765 67041 20479 54612 13411 36837 69983 53082 43589 278653. State your conclusion.

What is the probability of a student in a class of 25 getting picked at random at least twotimes if the teacher calls upon 5 students that class period?1. Describe how you will use a random number table to conduct this simulation.2. Show four trials by clearly labeling the random number table given below. Specify theoutcome of each trial.37542 04805 64894 74296 24805 24037 20636 10402 0082208422 68953 19645 09303 23209 02560 15953 34764 3508099019 02529 09376 70715 38311 31165 88676 74397 0443612807 99970 80157 36147 64032 36653 98951 16877 121713. State your conclusion.4. Conduct 50 trials using your calculator (randInt(1,25,5)) and determine the percent of timesthat a student was called upon at least 2 times in 5 attempts.
