Please show us what you have tried and exactly where you are stuck.A dice was thrown for 6 times.What is the probability that at least 5 was showed for 5 or more times?
My first step would be to restate the event like this:A dice was thrown for 6 times.What is the probability that at least 5 was showed for 5 or more times?
Like Dr. P said, find the probability of 5 or 6 showing first. Then work towards the combined probability by finding [MATH](P)^5[/MATH].A dice was thrown for 6 times.What is the probability that at least 5 was showed for 5 or more times?
