A researcher studying correlations between smoking habits and stress levels assigns subjects numbers based on their behavior—'13' for nonsmokers with high stress,'24' smokers with high stress,'31' nonsmokers with low stress,and '42' smokers with low stress—if data reveals equal chances across behaviors,the chance subje...

Given that the probability a randomly selected student at Central High School is in a math club is 0.20 and the probability that a math club member is also in a science club is 0.30, what is the probability that a student selected at random from Central High School is in both clubs if it's known that the probability of...
