Question

In a survey of 1147 small-business owners, the following question was posed: Would you recommend working with a significant other? Fifty-five percent of those polled answered in the affirmative, whereas 45% answered in the negative. Assuming that this result reflects the view of all small-business owners, what is the probability that at least 8 out of 10 small-business owners selected at random will opine that it would be unwise to work with the significant other? (Round your answer to four decimal places.)

Explanation / Answer

n=10

prob of sucess=p=0.55

prob of failure=1-p=0.45

X=no of small business owner

P(X>=8)=P(X=8)+P(X=9)+P(X=10)

                =0.09956
