A random sample of 8 people is chosen. Suppose X = number in the sample with high blood pressure. 2 D) What is the probability that not all 8 people will be found with high blood pressure? A) Here X has a binomial distribution. What are n and p? B) What are the values that X can take? C) What is the probability that exactly 3 people will be found with high blood pressure? dantn in a city iog regularly, A random sample of size 200

Explanation / Answer

Solution- (a) P(Women) = 0.59

P( democrat) = 0.5

P( Women and Democrat) = 0.29

Required probability = P( men) = 1- P(Women) = 0.59

= 0.41

(b) Required probability = P( democrat and men) = 1- P(Women and democrat ) = 0.29

= 0.714

(c) Required probability = P( women | democrat )

= P( Women and Democrat) /  P(Women)

= 0.29 / 0.59

= 0.492
