Question text

7 (a) % = {students in a group} M = {students who pass the mathematics test} S = {students who pass the science test} 142 students are in the group. 105 students pass the mathematics test. 82 students pass the mathematics test and pass the science test. 17 students do not pass the mathematics test and do not pass the science test. M S (i) Complete the Venn diagram. [2] (ii) Find n(M,S). ................................................. [1] (iii) One of these students is picked at random. Find the probability that this student passes the science test but does not pass them athematics test. .................................................
