[31andsmoke] What is the probability of randomly picking someone from the study who is 18-22 yrs old or is a non-smoker? [18orNS] What is the probability of randomly picking someone from the study who smokes, given they are 23-30 yrs old? [Sgiven23] note: answer in decimal form and round to 3 decimal places
