Asked by Sherri
If the probability of a dancing lady accepting an initation to dance is 0.18, find the expected number of ladies you would have to ask before one accepts.
I think that the answer is: 1(.18)+2(.18)+3(.18)...7(.18)+8(.18)+9(.18)=8.1
*round answers to three signifcant figures*

? The first one could accept. So one.
What certainty of accepatnce are you seeking? 90Percent? 99 Percent? There is a probability you could ask 50 without getting an acceptance. Your method is not right, but the basic question remains, with what certainity?
