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?

In math class, students must randomly draw a card that contains an equation that they must graph on the board.If the cards contain the equations 2y = 4x + 2, x(x + 1) = 0, 2x + y = 0, x = 2y , x2 + 1 = 0, and y - 2x = 0, then what is the probability that a student will graph a line whose slope is 2?
