Question

A study presented by Snee (1974) considered the relationship between eye color and hair color. Find the probability of randomly selecting a person with Blue eyes. Find the probability of randomly selecting a person with Red hair and Blue eyes. Given that the person has Red hair, find the probability that he/she has Blue eyes. Find the probability of randomly select a person with blond hair or green eyes. Are "Red hair" and "Blue eyes" independent? Verify mathematically. past year, 13% of businesses have eliminated jobs. If 35 businesses are select find the probability that more than 6 have eliminated jobs during the last year

Explanation / Answer

a) probabilty =215/592= 0.3632

b)probabilty =17/592=0.0287

c)probabilty=17/71=0.2394

d)probabilty =(127+5+29+14)/592=0.2956

e)P(blue eyes|red Hair)=0.2394

which is not equal to P(blue eyes)=0.3632

hence they are not independent
