QUESTION 17 There is a 10% probability a new art student will have an exhibit in the end of year show, If the new student has an exhibit in the end of year show, there is a COM probability that the student will graduate from the program. What is the probability a new student has an exhibit in the end of year show and does graduate from the program? O PfArt Show | Graduate) = (0.10) + (0.60) O PiArt Show / Graduate) = (0.10) + (0.60) O PiArt Show ( Graduate) = (0.10)*(0.60) O PIArt Show | Graduate) = (0.10).(0.60) QUESTION 18 About 40% of the first-grade students in a particular school are awarded a reading certificate at the end of the year. If a student is awarded the reading certificate, there is a 30% probability that the student will be accepted into the second grade gifted class. What is the probability that if a student is awarded the reading certificate that they are then accepted into the second-grade reading class? O P(Second Grade [ Reading Certificate) = (0.40) + (0.30) O P(second Grade) = (0.30] O P(second Grade) -(0.40) * (0.30) O P(Second Grade | Reading Certificate) = (0.30) QUESTION 19 esearchers are studying whether eating more than 1500 calones a day is related to obesity.
