- 3THE STUDENTS IN MR HENLYS CLASS PREDICTED THAT IF THEY EACH ROLLED A DIE 90 TIMES THE RESULT OF 1 OUT OF EVERY 6 ROLLS WOULD BE A 5
THE STUDENTS IN MR HENLYS CLASS PREDICTED THAT IF THEY EACH ROLLED A DIE 90 TIMES THE RESULT OF 1 OUT OF EVERY 6 ROLLS WOULD BE A 5. Each student then completed the experiment which result best supports the prediction of getting a 5 once out of 6 times. ( the question didnt say how many students were in the class)You need to finish the problem.

. In a group of 150 students, more students are taking a math class than are taking a science class this semester. If 80 are taking a science class and 25 are not taking either math or science this semester, what is the minimum number of students who could be taking both math and science this semester?
