Hello math forum.
I have a question.
What are the odds of a number between 1 and 152 being selected 6 Times in 15 chances?
The reason we ask you to show some work is to get some idea what the difficulty you have. Your question can be read at least two ways.
1) Given a number from 1 to 152, what is the probability that number would be randomly and independently selected exactly six times in 15 chances?
2) A number is selected from 1 to 152, what is the probability that same number would be randomly and independently selected exactly 5 more times in 14 chances?
The answers are similar but not the same.
What do I do with this number? I can't multiply that by the other two numbers in the equation which are
15/6 = 2.5
151/152 to the ninth power = .942323960625871
How do I compute these three numbers using scientific calculator??
