Consider the experiment of rolling 5 fair dice. You “win” if all the dice show different numbers. I have to decide in advance how many times to repeat the experiment. I will be very happy if I win at least once. What is the least number of times I need to plan to repeat the experiment so that my probability of winning at least once is more than 99%? So there is an equal chance that one of six possibilities are possible for for each dice roll. The first roll will have a different number = 1; 2nd is different 5/6, 3rd is 4/6, 4th is 3/6, 5th is 2/6 and the 6th is 1/6....so is the probability just the multiplication of all the chances and how do I get to 99% confidence?
