Classical Approach To Probability question
Posted 10-30-2009 at 08:11 AM by David_langstaff
Hey all, I am having a real problem whit a probability question that looks easy but is giving me a real pain.
The question goes, "A coustomer randomly selscts 6 doughnuts form 58 doughnuts of which 8 contain jelly. What is the probability that she selscts none of those containing jelly?
I am using the classical approach to probability to answer the question.
What I have done is to figure out the probability of her picking 1 nonjelly doughnut if she randomly selects using 50(nonjelly)/58total doughnuts= .862069
given that the probability that if she picked one doughnut and it would be none jelly is .862069 I figure that to find out what the probability of her picking 6 none jelly doughnuts I shoud raise .862060^6=.410442.
Does that sound right to anyone or am I making this to complicated
